I think that's a great idea. Yes, anonymity is required so people can speak freely without fear of retribution. But you have to also consider what it's like to be the recipient of those anonymous actions... People care about this community, and they're sharing their opinions in good faith -- they're putting themselves out there. So I think a downvote should require at least an equal commitment -- maybe a downvote with an (anonymous?) comment of explanation.... Maybe the downvote-with-comment could also be downvoted (with that new downvote affecting the karma of the original anonymous down-voter?)
