I personally would rather see a three control system, upvote = i like this; disagree = I disagree; and downvote = person is being a jerk. I think that is the issue people upvote to say I like this so it is easy to see the downvote as the opposite as opposed to a tangential, this is abusive. I think a three control system would clarify it. Unlike the upvotes and the downvotes I think the karma of I disagree should be displayed and people should be able to set personal thresholds on disagrees before they are greyed out.
