Facebook debuts book exchange program

Are you familiar with Facebook? It's a social-networking site similar to MySpace, but focused more on the college crowd (although it recently was opened to the public, and non-students are free to join. Current membership is about 30 million).

Anyway, Facebook has added a "book swap" feature that should drive some additional business to Amazon Marketplace. Users can list books they're interested in buying or selling by punching in the ISBN. Facebook is charging no fees or commissions for listing or selling books. If the book isn't listed by another Facebook member, members are referred to the book's Amazon page.

If you're already registered at Facebook, here's the link for the Marketplace Book Exchange.
