I just deleted my account on Facebook today. I don't even know why I made an account in the first place (social pressue, anyone?), but it got so f***in annoying, I mean the way everybody exposes their lives for everyone-else to see (and expects someone to care). For f***s sake, nobody cares what you ate for lunch! :
I totally know what you mean. And if you expose yourself on such a site, don't be surprised if some people take advantage.
