I'd like to see voting scores as a way to compare posts to each other. If you search and get several responses, it would be nice to think that there is a correlation between the votes and how good the answer is. So if you had 20 responses you could say well that ones average vote is higher so its at least more likely (thoeriticaly) to be a better, more thought out answer. I suppose now you have the same thing, but people can only vote ++ or --, so you don't get a feel for quality, just overall weather it okay or not.

I think that at least removing XP from the equation would stop people form ++'ing just because and only vote when the post realy screams "I'm good!' or "i suck!"
