Facebook

I don't bother creating my own Facebook account, i just use my friend's account from time to time. I use it to check out some pictures of girls in my class.
 
Facebook is very useful for organising parties. Its not better than a forum for this, but because all my friends use it, any changes/messages will actually get read.

The applications are rubbish, i hate them. I do have one or two installed though : / iLike for example.

Myspace is for emos! Boo...
