Instead of just scores, I'd like to see both how many upvotes and how many downvotes a comment has got. I second the suggestion to colorize the most upvoted or controversial comments. However I think the issue with simple scores is that they cram together agreeability and usefulness of a comment, which should be kept separate. That way, users which just agree with an opinion would be able not to influence the usefulness score of a comment.
