Mostly, though, I love their FAQ. Anyone with the policy: "If you post something that we, in our sole judgement deem to be offensive, spammy, trollish or otherwise uncultured, we may: disable your account, delete the question or change the question to make fun of you" has the right attitude in my book.
And the site motto -- "If you make a stupid choice because a website tells you to, it's your own damn fault" -- is so very, very right...
