		<description><![CDATA[Hi Leonard,

I&#039;m going to ignore, for the moment, your introductory sentences.  You are clearly trying to be inflammatory here, and congratulations, you have achieved your goal.

Let me make this exceptionally plain - eBay cares about collectors.  eBay cares a disproportionate amount about collectors.  eBay cares about collectors more than any other major internet site, and always will, even though collectors and collecting make up an increasingly small portion of eBay&#039;s business. 

You can still &quot;kick out&quot; the junk radios through keywords and advanced search terms.  As I explained in my post, Best Match is a sort, NOT a filter.  You can still filter to your hearts content.  

Here is the good news - &quot;time remaining&quot; is a factor in the Best Match sort.  The factors for Best Match can be tuned PER CATEGORY.

That means that if it proves true, through experiments, that collectors do best with a sort that is 100% Time Remaining, then eBay can set Best Match in those categories to be exactly that.

However, don&#039;t hold your breath.  While you claim to speak for all collectors, eBay will hopefully be looking at the shopping and purchasing results for their buyers, rather than just taking your word for it.  It&#039;s incredible unlikely that a sort based on a single variable, like time remaining, will prove to be optimal.

In the future, Leonard, I would highly recommend toning down the invective, and focusing more on the questions and statements you want to make.  Like permacrisis, it seems like your primary interest here is picking a fight.  Fighting here about eBay really isn&#039;t warranted.  I don&#039;t work for eBay anymore, and I don&#039;t speak for the company in any shape or form.  I&#039;m not a journalist, and this is not the forum to resolve your issues with eBay.  

This is just one topic on my personal blog.

		<description><![CDATA[Ho hum. You have a wonderful collection of fancy theories. But you had to develop those to get paid, didn&#039;t you? The fact is, however, that anyone who COLLECTS anything and now stumbles on eBay for the first time will most likely lose patience and leave before he figures out what&#039;s going on and turns off your nasty Best Match. Not to mention the &quot;New Search&quot;, which is simply a horror for all collectors and will drive us away in droves if implemented.

     Did your employers decide to throw away the collector buyers and sellers? If not, you have been very stupid in what you have done. A beginning collector wants and needs to see the things in his category--mine is old radios--spread out before him in the order they are closing; in other words, in all their exciting randomness. Or maybe, once he&#039;s a bit sophisticated and looking for a bargain, he will want to see things in the order of their listing (for &quot;Buy it Now&quot; items.) In the former case he might find something cool that&#039;s just about to close. I remember how exciting that was! In the latter case he might snag a bargain before anyone else sees it. 

    Whatever the individual&#039;s method of trolling for collectibles, it does not include buying want a bunch of people who don&#039;t know the field have preferred. In the field of old radios, for example, all my searches have to to explicitly kick out all replica radios: Non-collectors love a nice plastic &#039;30s-look radio. They are worthless to me. 

   The collector, in other words, wants to see a nice random spread of things in his favorite category. Seeing this when he is a novice will help him form an understanding of the available models and their usual prices. Later, seeing this lets him deploy his expertise to find misnamed gems, etc. 

    Under the traditional eBay search the collector gets to be the fisherman all collectors inherently are. Learning about the fish and finding them on your own is most of the fun. Certainly no fisherman worth his salt wants to have some third party swim up and cram some fish on his line that he doesn&#039;t want, just because a bunch of other folks do.  I resent the fact that the founders of eBay built a collectors&#039; paradise (on which I have happily spent many thousands of dollars), and now you people are crapping it up in order to sell more everyday commodities people could buy anywhere else at all.

		<description><![CDATA[permacrisis,

I don&#039;t know what to really say here except that I believe you are almost completely and totally wrong on all counts save one.  

The best accounting software is not actually built by accountants.  The best music software is not actually built by musicians.  The best CAD software is not actually built by architects.  In a perfect world, maybe these type of specialists would actually know how to design and build software.  Maybe they would if they invested part of their lives studying the topics and issues necessary to understand the technology and user experience issues involved.   But then again, if they did that, they might not be as good at accounting, music, or architecture...

In the real world, we have to find a way to get the insights from actual users of software and provide it to the people who have expertise in both designing and building it.  To do that, you need open and honest communication between customers and providers, and that communication cannot happen without a high degree of trust between the parties involved.

Best Match &lt;b&gt;does not remove keyword search&lt;/b&gt;.  It just changes the sort order.  Period.  So, your argument would be more relevant to a debate about different technologies for search recall than about sort order.  Best Match &lt;b&gt;does not filter anything&lt;/b&gt;.  It is not a filter.

You are, of course, correct about the item title.  You can learn a lot about a seller from it, and Best Match actually uses the title keywords to inform it&#039;s relevance algorithm.  Once again, Best Match does not hide any titles.  It does not hide any items.  It just changes the order.

To argue that eBay employees &quot;culturally despise&quot; auctions is an absolutely ridiculous and inflamatory statement.  Auctions are the lifeblood of eBay, and everyone is immersed in that at eBay.  

Most importantly here, your post displays an incredible lack of respect for the hard working men &amp; women who work extremely long hours on a regular basis to make eBay the best possible for millions of sellers and hundreds of millions of buyers.  You are disparaging them, their efforts, and their motivations.  There is nothing good that is going to come from that type of toxic behavior.

Please don&#039;t post on my blog again.

		<description><![CDATA[Hi Adam,

Thanks for the reply - I do appreciate it! Yeah, I remember that you wrote, back on the EE board, that you are a seller and I figured you still are. It is that POV you have that makes you the perfect Brain for picking. LOL. You certainly don&#039;t have to depend upon your ebay sales for income (the techie field isn&#039;t that bad, is it?), but I do assume you have more insight into ebay sales than many/most/all of the top Execs.

I really don&#039;t have any assumptions about the ramifications of BM - even its direct impact upon (only) Collectibles. It is easy to see that it *can* be implemented into any collectible category with basically postive results. But, It&#039;s like you wrote... &quot;if done correctly, eBay will optimize Best Match on a very localized way&quot;.  It is that &quot;if&quot; word that has many of us worried. 

&quot;If done correctly, Best Match should always be optimizing itself...&quot;. Again, that scary IF word. I have to say that most Collectible sellers doubt that the ebay personnel involved have the necessary POV needed for such items. This viewpoint stems from the perception (by the sellers) that BM is fundamentally wrong for the collectibles arena. You probably don&#039;t agree with that statement, but do you understand from where it comes?

As far as Searching goes, I have faith in my buyers - both repeat and first-timers. They are a diligent bunch and they will wade through just about any roadblock encountered. Since I am incognito here, I can say it... I sell Old Junk. I love the stuff and so do my buyers. I have very little problem with scam buyers and other such troubles - if they buy it, they are truly interested in IT.

I have sold this Old Junk since the mid 70&#039;s from a B&amp;M store and did mail order by way of trade magazines. Later, this thing called the Internet allowed trade via Bulletin Boards, then to Prodigy ads and finally to ads on AOL with a puny link to a pix on our &#039;personal page&#039;. Oh yes, we thought we were really high-tech back then. I was a little late to ebay (1999), but I did/do have some experience with &quot;unseen item trade&quot;.

I know a few things about a collectibles buyer, because I am one and I have dealt with them for a while. I know they don&#039;t want to be lead around, directing their attention to whatever it is that YOU want to show them. They want to look, browse, hunt, dig, scrounge while searching for a dozen things they have in mind. But wait! they just found something else and they just gotta have it. That is serendipity - not a leopard skin iPod cover!!



It would not matter how much data the BM machine has collected and collated from the entire ebay listing DB, nor for how long it has collected it, when a scarce / rare item comes along, it&#039;s Relevancy and Desirability scores will be low, or quite possibly, into the negative. Now, I make no assumptions about how these factors *may* be overcome, or if this scenario is even considered &#039;important&#039; by ebay. I am simple stating the general perception of some sellers. (or the forgone conclusion of the vast majority of collectibles sellers - but that would be presumptuous of me)



I realize (and others do also) that ebay can institute controls to affect the above example. But, that&#039;s the problem, Adam. The fact that something has to be Done, to correct something else that was previously Done. And, whatever that &#039;Done&#039; accomplished, will prolly need to have another Done implemented to correct yet another issue.

A river with a dam. A hole is drilled to allow water to flow. Downstream, another dam is erected to stem the flow. Yet another hole to allow water, and on and on and on... Just leave the dang river alone, to begin with. But that just ain&#039;t gonna happen - the need (real or imaginary) to Showcase and also to Disadvantage is at hand, and it will be done. Period. So be it.

Then we are back to the point that BM is fundamentally wrong for the way that Collectibles Buyers shop. Period. I am but one voice, yet many others say the same thing on the boards and ebay chooses to ignore us. You have to know, that is taken as a signal that we are Correct and they have no answer. Maybe that isn&#039;t factual, but it is the implication that many sellers believe. Their continued silence is our Proof. That&#039;s how it works, in human nature.

Maybe they simply chose to not answer- not yet, anyway. Which begs the question, do We really matter to ebay? As an aggregate, Yes, but an aggregate number excludes the Scarce / Rare / Unique and that is our concern. It should be ebay&#039;s concern, as well. Peeps may flock to ebay for the consumer electronics and gadgets, but it is the serious collectors that come back, time and again (through any roadblocks, remember?).


With BM in force, the serious Collectibles buyer cannot search for and find that Treasure amid all the scattered clutter and hodgepodge of listings. Not easily, anyway. But they will try. Again and again. So, what about the newbie just coming to ebay to &quot;take a look around&quot;? When they browse to the collectibles category, will they see that Sky King secret decoder ring, or a screen-full of leopard skin iPod covers sorted with the scam seller as the next to last item on page 5? (with that Sky King ring being the last item)


I really don&#039;t see any Fix or Optimization that will keep BM from damaging the collectibles arena. It, like ebay&#039;s metrics, deal in the *aggregate* and that is not Collectibles; not their Supply, not their desirability factor, not even in the percentage of buyers looking for them. Quote: &quot;Best Match will only be successful if it delivers more bids and more sales, in the aggregate, to the marketplace, period.&quot; Again, I say, what is good for the aggregate, is not necessarily good for the individual seller.

When enough individual sellers have lost enough money - when enough individual buyers have lost enough patience... they will become an aggregate. It&#039;s only a matter of When, the &#039;If&#039; was passed long ago. BM will speed-up that process. Ebay&#039;s monopolistic stance seems to be hard-coded and what now appears as a Slide/Downturn to TPTB, has been obvious to the sellers for a long time now. We believe that we actually have some insight into this Buyer/Seller/eCommerce thingy. We warn - Fraud, Scams, Hijacks in 2004. We were/are ignored. We have been proven correct every time - ebay REacts to threats in 2006-7. There&#039;s no pleasure in being Right.

WARNING: Best Match is hazardous to the Collectibles arena.

That warning is not meant to be taken literally, exclusively, for just the items themselves. The Perceptions of the sellers and buyers are also being impacted. The damage is done, and continuing to grow, and ebay&#039;s failure to address these issues does nothing but add to the damage. The old ebay mindset of &quot;wait it out&quot;, is not just failing, it is causing the &#039;dragon to eat its tail&#039;. Even though ebay is aware that the marketplace is drastically changing, the only changes they make in their response to customers&#039; pleas is to be LESS forthcoming and receptive. Classic 900-pound gorilla methodology. A diet is long overdue.

I agree that ebay asked the right question... I just wish they had asked the opinions of a large amount of sellers. Maybe all of them.

Tony

P.S. Adam, sorry this reply is almost blog-length itself. I am (secretly) hoping that you still have some input, in whatever fashion, to the ebay peeps in charge of this roll-out. And if you don&#039;t, just keep that a secret. I don&#039;t want to abandon Hope, just yet.]]></description>

<p>&#8220;If done correctly, Best Match should always be optimizing itself&#8230;&#8221;. Again, that scary IF word. I have to say that most Collectible sellers doubt that the ebay personnel involved have the necessary POV needed for such items. This viewpoint stems from the perception (by the sellers) that BM is fundamentally wrong for the collectibles arena. You probably don&#8217;t agree with that statement, but do you understand from where it comes?</p>
<p>As far as Searching goes, I have faith in my buyers &#8211; both repeat and first-timers. They are a diligent bunch and they will wade through just about any roadblock encountered. Since I am incognito here, I can say it&#8230; I sell Old Junk. I love the stuff and so do my buyers. I have very little problem with scam buyers and other such troubles &#8211; if they buy it, they are truly interested in IT.</p>
<p>I have sold this Old Junk since the mid 70&#8242;s from a B&amp;M store and did mail order by way of trade magazines. Later, this thing called the Internet allowed trade via Bulletin Boards, then to Prodigy ads and finally to ads on AOL with a puny link to a pix on our &#8216;personal page&#8217;. Oh yes, we thought we were really high-tech back then. I was a little late to ebay (1999), but I did/do have some experience with &#8220;unseen item trade&#8221;.</p>
<p>I know a few things about a collectibles buyer, because I am one and I have dealt with them for a while. I know they don&#8217;t want to be lead around, directing their attention to whatever it is that YOU want to show them. They want to look, browse, hunt, dig, scrounge while searching for a dozen things they have in mind. But wait! they just found something else and they just gotta have it. That is serendipity &#8211; not a leopard skin iPod cover!!</p>
<p>It would not matter how much data the BM machine has collected and collated from the entire ebay listing DB, nor for how long it has collected it, when a scarce / rare item comes along, it&#8217;s Relevancy and Desirability scores will be low, or quite possibly, into the negative. Now, I make no assumptions about how these factors *may* be overcome, or if this scenario is even considered &#8216;important&#8217; by ebay. I am simple stating the general perception of some sellers. (or the forgone conclusion of the vast majority of collectibles sellers &#8211; but that would be presumptuous of me)</p>
<p>I realize (and others do also) that ebay can institute controls to affect the above example. But, that&#8217;s the problem, Adam. The fact that something has to be Done, to correct something else that was previously Done. And, whatever that &#8216;Done&#8217; accomplished, will prolly need to have another Done implemented to correct yet another issue.</p>
<p>A river with a dam. A hole is drilled to allow water to flow. Downstream, another dam is erected to stem the flow. Yet another hole to allow water, and on and on and on&#8230; Just leave the dang river alone, to begin with. But that just ain&#8217;t gonna happen &#8211; the need (real or imaginary) to Showcase and also to Disadvantage is at hand, and it will be done. Period. So be it.</p>
<p>Then we are back to the point that BM is fundamentally wrong for the way that Collectibles Buyers shop. Period. I am but one voice, yet many others say the same thing on the boards and ebay chooses to ignore us. You have to know, that is taken as a signal that we are Correct and they have no answer. Maybe that isn&#8217;t factual, but it is the implication that many sellers believe. Their continued silence is our Proof. That&#8217;s how it works, in human nature.</p>
<p>Maybe they simply chose to not answer- not yet, anyway. Which begs the question, do We really matter to ebay? As an aggregate, Yes, but an aggregate number excludes the Scarce / Rare / Unique and that is our concern. It should be ebay&#8217;s concern, as well. Peeps may flock to ebay for the consumer electronics and gadgets, but it is the serious collectors that come back, time and again (through any roadblocks, remember?).</p>
<p>With BM in force, the serious Collectibles buyer cannot search for and find that Treasure amid all the scattered clutter and hodgepodge of listings. Not easily, anyway. But they will try. Again and again. So, what about the newbie just coming to ebay to &#8220;take a look around&#8221;? When they browse to the collectibles category, will they see that Sky King secret decoder ring, or a screen-full of leopard skin iPod covers sorted with the scam seller as the next to last item on page 5? (with that Sky King ring being the last item)</p>
<p>I really don&#8217;t see any Fix or Optimization that will keep BM from damaging the collectibles arena. It, like ebay&#8217;s metrics, deal in the *aggregate* and that is not Collectibles; not their Supply, not their desirability factor, not even in the percentage of buyers looking for them. Quote: &#8220;Best Match will only be successful if it delivers more bids and more sales, in the aggregate, to the marketplace, period.&#8221; Again, I say, what is good for the aggregate, is not necessarily good for the individual seller.</p>
<p>When enough individual sellers have lost enough money &#8211; when enough individual buyers have lost enough patience&#8230; they will become an aggregate. It&#8217;s only a matter of When, the &#8216;If&#8217; was passed long ago. BM will speed-up that process. Ebay&#8217;s monopolistic stance seems to be hard-coded and what now appears as a Slide/Downturn to TPTB, has been obvious to the sellers for a long time now. We believe that we actually have some insight into this Buyer/Seller/eCommerce thingy. We warn &#8211; Fraud, Scams, Hijacks in 2004. We were/are ignored. We have been proven correct every time &#8211; ebay REacts to threats in 2006-7. There&#8217;s no pleasure in being Right.</p>
<p>WARNING: Best Match is hazardous to the Collectibles arena.</p>
<p>That warning is not meant to be taken literally, exclusively, for just the items themselves. The Perceptions of the sellers and buyers are also being impacted. The damage is done, and continuing to grow, and ebay&#8217;s failure to address these issues does nothing but add to the damage. The old ebay mindset of &#8220;wait it out&#8221;, is not just failing, it is causing the &#8216;dragon to eat its tail&#8217;. Even though ebay is aware that the marketplace is drastically changing, the only changes they make in their response to customers&#8217; pleas is to be LESS forthcoming and receptive. Classic 900-pound gorilla methodology. A diet is long overdue.</p>
<p>I agree that ebay asked the right question&#8230; I just wish they had asked the opinions of a large amount of sellers. Maybe all of them.</p>
<p>Tony</p>
<p>P.S. Adam, sorry this reply is almost blog-length itself. I am (secretly) hoping that you still have some input, in whatever fashion, to the ebay peeps in charge of this roll-out. And if you don&#8217;t, just keep that a secret. I don&#8217;t want to abandon Hope, just yet.</p>

		<description><![CDATA[Hi Tony,

Wow!  Quite a comment.  I really appreciate the kind words.  Although I love the vibrancy and excitement of the quickly growing LinkedIn community, I still miss those conversations on eBay, and of course, I&#039;m still a fairly active eBay seller myself.

I think you are making a few assumption about Best Match that aren&#039;t quite right - if done correctly, eBay will optimize Best Match on a very localized way - Best Match will be different across different queries, different categories, different countries - even potentially different buyers!  It will depend on both long term and short term trends and behaviors.  If done correctly, Best Match should always be optimizing itself to show the items that the buyer is most likely to buy.

Remember, the advanced buyer is going to come in, and choose other sorts - by time, by price, etc.  They may even know how to do advanced searches with special keywords and controls (you should see my buying searches!)

Best Match will only be successful if it delivers more bids and more sales, in the aggregate, to the marketplace, period.  I would expect it&#039;s approach to doing this will vary significantly in collectibles vs. clothing vs. electronics vs. media.

I notice the comment on eBay Express... :)  Let me tell you, with eBay Express we spent our time on two things:
1) How to make it literally painless for as many sellers as possible to adopt.  (For most sellers, they literally had to do nothing).
2) How to make the overall purchase experience as good as possible.

As JD &amp; MW stated on the call today, a lot of the new technology, new thinking, and feature concepts from eBay Express are now forming the basis for great improvements to eBay.com.  Of course, they will be modified to fit an auction environment.  

But in my local world view, eBay Express was the first time that eBay said, whole heartedly, &quot;How do we make the best buying experience possible?&quot;

And regardless of the answer, that question is very right.

		<description><![CDATA[Hi Adam, you and I had a dialogue on the EE board quite a while ago. It was very informative for me and it, along with your other postings, displayed the positive nature of your ideals and character. I was, and still remain, truly sad that you left ebay. Their loss, is our loss. I value your opinion and ask you to comment, if you can, on the following.

I joined ebay in 1999; I do understand the obstacles that ebay faces in Relevant Finding (in my limited, user way). Yes, Fixed price is the du jour (we store sellers have been saying that for some time now!), but what about Auctions in all this Best Match manipulation? What about re-invigerating the Auction experience? Won&#039;t showing the auctions out of time-ending sequence have the potential to cause fewer bids?

What about the unique, scarce and truly rare collectibles and antiques, as they are practically forced to use the auction format? As scarce items, any group of them would generally make up a Small Subset, to begin with, and should therefore be shown in a somewhat less-BM-scattered display. But, they could be vunerable to inclusion of non-relevant listings, thereby being hidden via a massive amount of unwanted search-result listings.

It is obvious the BM technology is geared towards manipulating the search results of a huge DB of similar / like items, which simply shouts NEW; as in Commodities. Is the entire Collectibles arena destined to be in that group that you write, &quot;others will do worse&quot;?

&quot;...to ensure that it results in higher sales for the marketplace and happier eBay buyers.&quot; That statement fragment (of yours) conveys the basic premise of BM. It is repeated throughout your post, in several paragraphs with various wording. I don&#039;t doubt that that is its intended purpose, but will auctions suffer because of it?

If more auctions receive bids, then the goal is achieved. But, if MORE auctions receive fewer Multiple bids (than currently) because ending-times are scattered, the Marketplace will gain as a whole, while the individual sellers suffer. The wealth will be spread farther, the bidders (buyers) will get really great deals; ebay will collect on additional FVF fees due to increased STR; ebay&#039;s metrics will increase. It&#039;s a win-win for the buyer, for ebay and, possibly, the Commodity seller.

For the seller that starts a $300 Nippon vase at $9.95, it doesn&#039;t look so good. The two arenas - Commodity and Collectible - are diametrically opposed when it comes to a search function. Your 4-step search result function is still valid for Collectibles, as long as a functioning category structure is also in place to allow for farther segmenting when a large volume is returned.


Is it time for ebay to finally make the Big Break and have two sites? You know, what EE was intended to be, but sellers refused to adopt.(wink) Perhaps you could do a whole posting about BM versus Colectibles... sorry, make that BM and Collectibles. Thanks Adam!

		<description><![CDATA[Actually, it&#039;s not that simple.  I could write a whole post on the complexities of both gaming the system, and trying to detect gaming.  But you can&#039;t just use purchase events for ranking to produce high quality data - you can game purchases in some ways more easily that clicks or watches because purchases happen in far lower volumes than clicks or watches.  

Like Google, eBay will have to invest significant resources in maintaining the quality of the ranking algorithm over time, to both adapt for changes in the market and for fraudulent abuse.

		<description><![CDATA[I hope eBay already had ranking manipulation filters in place. The patent paper specifically mentions keyword search, click-through and adding to watch list as being part of the algorithm.

The only true measure of popularity is a keyword search that actually leads to a sale with confirmed payment.]]></description>
