Interesting because I'm experiencing part of the problem that others are discussing here. You see I disagree with your idea but there is no way to indicate that w/o downvoting (which I didn't do). And to simply reply by saying "I disagree" isn't appropriate either. And maybe I don't want to take the time to detail exactly why I disagree but would like you to know that? But you don't because all you see is a net number positive or negative. (By the way I would summarize why I disagree now that I've written the above as simply that it seems like a "last man over the bridge" advantage. I mean it's entirely possible that some distinguished person whose vote should count would be greatly disadvantaged by the weighting system you propose.) I hate to complicate things but there doesn't appear to be anyway to solve this issue w/o the ability to indicate more clearly what you feel is positive or negative about a comments. One up/down button simply can't cover everything.
