21 Places to Go When You're Sick of Facebook
Buzznet
Who it's for: People who love popular things, those who hope to be popular.
What we like: Buzznet avoids the traditional social network model by mixing it with music news, artist pages, user videos and photos, and concert listings. What's unique about the site is that member profiles can receive "buzz" from others in the form of views and comments, making you "grow" in popularity. Sure, there's a lot of self-promotion going on here but you can also find lots of really cool people, bands, and groups that you might miss otherwise.
