About a year ago, I mentioned the problem of "bandwagon upvoting"

So I'm really glad to see this and hopeful it works out. I think hiding the votes is better than a hard upper vote limit, as it is more organic. I'm really curious to know after the experiment how this affects the voting behavior (more votes, less votes, more for lead, less, etc)
