Possible Duplicates:
cast multiple votes with cost
Should we have a small number of Supervotes per day?

I've often wished that Stackoverflow would let us spend more than one vote on answers
... and I agree, so here's a modest proposal -- for really exceptional answers, allow people a second up-vote, but at an expense to their own reputation. To prevent abuse, you could make it cost 2 11 reputation (or more), so people can't use multiple accounts to try to game the system.
If it's something that would only be used for truly great answers, I could even see spending 5 20 reputation (which is more than 0.5% 2% of my current rep on any of the sites) to give them a +2 upvote.
Of course, I have no idea what it'd take to actually implement something like this, and there might be other social issues that I hadn't considered, but I just thought I'd toss it out there for discussion.
update : okay, I should've verified the amount of reputation gained by upvotes. My goal was to make it cost 2 to 5 times the benefit gained from an upvote, so I screwed up.
