I think it's mostly worthless. If you have nothing better to do with your life then talk about yourself and help others talk about themselves then it's probably a feast. I have thought about posting every book or album I read or purchase to FB, it would be more interesting then any "cgod has checked into a random shitty restaurant." Like most peoples blogs, I find that FB makes every one seem less like someone I wish I knew then having a real conversation with them. An odd thing, plenty of people I don't really care about have friended me on FB (this is aside from the real friends I have that have friended me), but the half a dozen people I would really like to reconnect with are unfindeable on their platform. I don't know if there is some kind of anti-FB quality in people I value or what.
