I have a Facebook page, and I had a MySpace page as well for awhile, but ended up deleting it because I didn't really like MySpace. Facebook is also rather inane, but its an inanity that I can deal with. I don't have a lot of apps, and I'm really selective about my friends -- since your "friends" are the ones who can see your page, I don't have friends on Facebook who aren't my friends in real life. As a result, I have a much smaller friends list than a lot of people, but I never feel weird about posting something on Facebook, since I know that only people that I really know and like will be seeing it.
