Frankly, I think it's more than just misogyny that plagues Digg. I never read the commentary anymore. To my mind, the need is for a new Digg community, or a more vocal community of us sane people.

Some of the reasons that I find Slashdot a bit better are the labeled moderation system and the karma system. They help keep some of the worst trolling off the site at the cost of encouraging a sort of groupthink.
