Even then, I think the scores for each should be bifurcated so that people can see the number of "worth reading" vs. "not worth reading" votes, and the same for agree/disagree. I think the practice should at least be modeled liked a number-line. The default is 0, neither an upmod or downmod. Just as it is, an upmod (or +1) should be given if the post was particularly interesting (not agreeable, interesting), and a downmod (or -1) should be given if the post was particularly non-interesting (not disagreeable, non-interesting). I think too many people only see the world as either +1/-1 with no option to just leave a comment alone.
