It'd be interesting to honor the codeforces users that love downvoting everything with a publicly visible position in a new feature that we shall call "Disagreeability Leaderboard". Moreover, we could reward them with unique titles that highlight their passion for putting others down.

Of course we can have a similar feature for upvoters that like to spread love and only use the downvote button when they find something particularly bad.

I think that features like this, along with monitoring upvote/downvote statistics more closely, will help us move towards a better contribution system, which admittedly has room for improvement.

Thoughts?
