I really like the Karma system. I think Karma as a way to decide user permissions is interesting (as is the case on hacker news). I also wonder if karma should decide the “reach” of a tweet, that way more respected users get to amplify their ideas and trolls do not. Downvotes is a contentious one, as we want to foster active debate. The issue I see with downvotes is that their ambiguous - you might downvote because you disagree with the statement OR because you don’t like the tweet.
