LinkedIn: A Billion Dollar Bet on Professional Networking

Hard to imagine that valuation. They claim their business model is based on ads and member revenues. Unlike other social networking sites, this site is in a niche market, and members don't spend as much time on the site. (not good for advertisers)
A million new members per month does not necessarily translate to a high revenue increase rate. Wonder what is the VC's exit strategy.
