Though I agree with the many commenters who have pointed out the abundance of password-guessing, I don't share their cynicism. The end result of all of this is that ~30 people who otherwise wouldn't have heard of LW have now given it a cursory glance. And look at the first comment here--it seems like we have prompted a handful people to enjoy thinking about rationality who might not have done so otherwise. Isn't that part of why the community exists, after all?
