On a related note: in my experience, I've always found people of the reddit community to be very smart, but also very negative, and very insensitive, vs. people on news.yc being smart, pragmatic, and at some times...irrational. This is based on real life interactions with coworkers as well as online.
Funny thing... I've stopped hanging around Reddit for the last few weeks, and my outlook on life has noticeably improved... I used to be a very cynical, see the worst in everything sort of guy, but once I distanced myself from others like this, I've found that everything is suddenly... better.
YMMV, but I'm not going to go back to being a reddit regularly anytime soon :)
