YouNow is a reasonably new social network based around the idea of broadcasting yourself and chatting to the people who log into your channel. It has about 150,000 broadcasters a day, which is an impressive figure. However, that's the only thing that I did find impressive. Very little by the way of search, and most of the broadcasters seemed to be in their early teens. Really couldn't find a whole lot to be excited about. If you're looking for something that works a little better, I'd be inclined to try Blab instead.
