When Facebook was down yesterday, I was surprised to see so many people on HN posting about it with what looked like the nervous energy of people in low-level withdrawal, because there is so much antipathy about it in threads like this one. It's possible that there's totally non-overlapping sets of HN users in both cases, but realistically I think most people just have a complex relationship with it: when Facebook is offline, it's a major event in their lives, but when it's back up, it's worthy of nothing but overt contempt. What most people (here, and everywhere) can't seem to do is just minimize the footprint of Facebook in their lives.
