Face-ing facts

Do any of you do facebook? I have had several people ask me if I do, almost expecting me to say yes. These particular people have been very excited about it, and can't stop talking about how many old friends they have found.

When Shane came home the other day and told me that he had opened a facebook account, I laughed--because he is so not into this kind of thing. He claimed that a friend had just signed him up and downloaded pictures from my blog. But, then, he was getting so many "requests" from old friends that it was almost funny. Do people look up other people on a regular basis? How do you find someone the very day that they open an account? Nonetheless, I was intrigued. So I opened one for myself. But I still don't get it.

Here's my question. What, exactly, is the point of facebook? I can see how you might find some people from your past--but then what do you do? Do you just add them as a friend and peek at their account every once in a while? Or do you send them messages? Or actually try to contact them? I'm not really getting the point.

And for those of you who do it--what is your motivation? And does it take as much effort as blogging--because I just don't know if I have that in me...
