eBay just launched an application on Facebook called (unimaginatively) eBay Marketplace. As of now, there are only 250 people on the app so I’m guessing its only in beta. Otherwise just by encouraging the employees to get on, it would have a huge number of users.

There are a few cool features. For one, you can actually “push” an eBay item to your friends’ watch list. For another, you can solicit comments from friends on items you are looking to bid on. All very cool. . . I was surprised a third party app hasnt been launched to do exactly the same and make some money off eBay affiliate program (damn, another item crossed off my crazy idea to-do list).

Another thought is that Facebook has it’s own “marketplace” application which is somewhat competitive with this ebay app. Wonder what they will do. Speaking of conflict of interests, given that Rock You’s “super wall” has become such a big hit, it is inevitable that Facebook enhance the its own “wall” application to allow embeded codes. . . When that happens, I wonder if people are going to start screaming the usual “extend and embrace” MSFT-ish rants about Facebook stealing ideas from its api partners.

Not letting eBay off the hook either, why hasnt eBay’s own social networking app “My World” been given the same the same functionality? My World is a 2001 implementation of a social network . . . ie more like friendster than myspace (win on personalization) or facebook (win on relevance).
