We commented on this just yesterday. Those who come off as douchebags are simply ignored here, so there's no incentive to do so. While being nice may not make you any money, it doesn't alienate people either, and honestly who really wants to alienate people? If you do, well maybe you deserve to be ignored yourself.

I think the biggest factor, and maybe I haven't seen enough of the bad side, is that the early adopters here are all such optimistic people, and as such are also very giving to others. And when you're in such company you tend to feel more optimistic and generous yourself. So it becomes something of a virtuous cycle.

Anyway, I enjoy it here, so I think I'll stay. It's fed something inside me that has been hungry for a very long time.
