eBay DevCon 2007 is all about "eBay Anywhere." (See my podcast interview with eBay's Max Mancini and John Donahoe.) This includes eBay on the desktop, mobile device, sites like Facebook and MySpace, blogs, etc. So what does this look? Here's a look at a few eBay-oriented Facebook apps (you may have to join Facebook to view the apps).

1) Patrick Shyu created with the help of Noah Kagan (http://www.linkedin.com/in/noahkagan) a tool that allows eBay users to display their auctions on Facebook (http://apps.facebook.com/ebaybook). I asked Noah if sellers could benefit by inserting affiliate links. He said no, but it sounded like a good idea. Be aware it looks like any Facebook user can enter any User ID at this point - Noah said it was only "the first draft" of the application.

2) Terapeak (http://www.terapeak.com) built an eBay search tool for Facebook so users can search eBay without leaving Facebook. Results are displayed right in Facebook, it's only when you click on a listing that you are taken to eBay (http://apps.facebook.com/finditinstantly).

3) I did a search for eBay on Facebook and found this: "Student Superstore (by Half.com an eBay company)." With this app, after searching, you're brought to an eBay results page, rather than displaying the results in Facebook, so it's not as advanced as the Terapeak tool.

I've also written about Ztail (http://www.auctionbytes.com/cab/abn/y07/m06/i07/s02) and Auction Ads (http://www.auctionads.com), services that let you push out listings to Web 2.0 sites.

While in some ways I'm intrigued, I'm not sure I see this idea of eBay Anywhere as positively as eBay does. And the idea eBay may be putting its fate (to get buyers) in the hands of affiliates is not a reassuring thought. I hope eBay will let developers work on such applications and that eBay will work on keeping its platform safe, reliable and stable. I have a feeling Web 2.0 could prove be a big distraction for eBay.
