physical contact? karaoke? the outdoors? What does that have to do with rationality? Genuine progress requires Weirdtopia, not just Eutopia.

Physical contact and the outdoors, at least, pattern-match to me as something that a) are inherently enjoyable to the typical human brain, and b) that the stereotypical LessWrong member, a somewhat geeky male, doesn't already do a lot of. Low-hanging fruit, I guess–although I should beware of stereotypes and pattern-matching, because I'm probably mostly wrong.
