4) Tell me there's a character limit, and what that limit is :) New feature: Why not combine the scoring with Flickr like tags. Instead of just being limited to increasing/decreasing an items karma, give me the option of increasing/decreasing tags, and the ability to add a new tags of my own which others could then vote on. This would probably be a good feature for Reddit as well. They could do away with the handful of subreddits they have and use this tagging scheme instead.
