Most of YouTube doesn't work as a social network, and most YouTube users don't use it for social networking. I don't find the argument from features compelling because so many different services have the same features. On a broad definition, there are millions of social networking sites, but on a broad definition, the term becomes so close to meaningless that it doesn't tell you anything useful.
