Meh they can work sometimes, I enjoy facebook a lot though.
I liked Myspace for a while, but then I got annoyed with girls flooding the bulletin board desperatly seeking picture comments (as if they were socially rejected if they didn't get any or something)

Facebook doesn't have that kind of stuff, but it is getting on my nerves with all the pointless applications that are coming out for it, but it's manageable because you can turn those notifications off
