Facebook/MySpace

What is the deal with the people who go to Facebook and MySpace? Like, what the heck? Why wouldn't I want to go outside, find some stalker person and then meet them in a dark alley at some time, when I can go to Facebook or MySpace and get the same thing? Exactly, and what is the point in this anyways? To make you feel good about the one friend you have when you sign up? When you meet somebody that is some stalker? Yah, what's really good about these websites? Wow. If somebody can explain this for me, I'd be happy to know. It's really lame, and people shouldn't use it. I have no clue why it's one of the most popular websites on the internet, and if somebody would care to explain this to me as well, it would be appreciated. Anyways...
