Can Peer-To-Peer Finance Work?

Dotnaught writes "Two companies, Prosper and Zopa, appear to be convinced that social networking can be combined with borrowing and lending. They're intent on using eBay as a model for listing and bidding on loans without the involvement of a bank. Call it peer-to-peer finance. There are already some 800 groups on Prosper ready to loan money to specific causes, such as the Apple User Group, 'a lending group for those wishing to purchase either a Macintosh or Apple iPod.'"
