Actually, slashdot manages pretty well. Considering the number of users they have. Their moderation system has matured over time. And the typical WTF, 'funny pics' and youtube crap that ruins other sites is isolated on http://idle.slashdot.org/ where it can harm no-one. I think it starts with comment moderation ( http://slashdot.org/moderation.shtml ). It's hard to get karma on /. by just fooling around, and you have to be a dedicated user to even get to moderate other comments. Contrary to digg where a sensible comment about X can be downmodded into oblivion by an army of 13 year old fanboys.
