Slashdot used probabilistic anonymized meta-moderation. I think that should be used to weigh people's karma. (So someone that is deemed very wise by the meta-moderators should have more "power".) I have no idea of the second order effects of this. Echo chambers are of course possible, just like without this. Maybe adding a third layer would help to reward people who help diversify and rationalize discussions, and so on.
