I used to participate in a bunch of other forums but nowadays read (mainly lurk) Talkbass. Recently I went back and visited a forum on bikes and bicycling that I've been a member of since 2003 and was surprised how contentious and mean-spirited it was there. I didn't remember it that way but maybe I've just been spoiled by Talkbass. Any ideas on why this place is so different than a typical Internet forum? I mean, people are really nice here.
