Dunno if you've seen it but there is an Episode on South Park, about Facebook.
Basically what happens is, there is a very unpopular kid who has 0 friends on Facebook, that is until Kyle decides to add him out of good faith.
As a result, Kyle loses all of his friends on Facebook.
Anyway, if you take a look at my Profile (http://n-europe.com/forum/member.php?u=371) I think you will see what I mean...
Sorry if I offend anyone, I am only joking.
