I love FB, it allows me to post pictures of the kids and keep all of the relatives updated, without actually having to interact with them. As a bona fide misanthrope, I love its convenience for staying in touch with people, but not TOO close.
People who get wrapped up in it or offended by what they read, are doing it to themselves. It's very simple for me to ignore the stupid crap on there, it doesn't affect my day at all.
