lol, rants on fb. I only use it to manage my social calendar. I don't think I've actually posted to my page in months.
I love Twitter, though. There's a bunch of crap on it, but you can kinda filter it out by being picky about who you follow. My feed is basically a giant news feed of people/topics I actually give a damn about. As opposed to FB, where I don't care what 99% of my friends are doing most times. It's great.
