I use Facebook basically for two purposes. Sharing and consuming denk mems, and for scheduling gatherings of friends that use Facebook (which is mostly all of them, because this is about all they use it for too).
People need to stop acting like these things are somehow controlling anything you do and realize that they're just tools. Do what you want with them.
If that's "not use it" for whatever reason, fine. I just wish people would stop with these nonsensical "I QUIT FACEBOOK AND NOW MY LIFE IS SO MUCH BETTERER" stories.
