ChatRoulette is a site that is getting a lot of attention. Some think it could be the "next big thing" on the web. The concept is simple. You chat via a webcam or keyboard with random strangers. If you don't like the one you're currently connected to, just click a button (or hit F9), and you're on to the next one. Maybe at some point you can find someone you like, have something in common with, or don't find incredibly repulsive.
