If it's possible to make both upvotes and downvotes anonymous, that will take the politics away from voting, and we would get a more accurate picture of what a post is truly worth. It would make the single biggest impact for PoB in a good way IMO. I'm sure many will see a post; think that's a bit overvalued, but don't want to downvote even a small amount due to having their name plastered up for all to see; it can turn tribal. I'm not sure how we would do that without taking voting off the base layer, but I don't think that's a good idea as anything to do with HIVE should be as secure as possible.

The last point you made on downvote curation is clever and accomplishes the same thing without the negative side effects. I'm in favor of doing it that way.
