Let me reward a good edit on my question/answer
This question made me think. When you up- or downvote a question (or an answer) all the points go to the original poster. But there have been plenty of occasions where I thought a question was worthy of an upvote, except that when I looked at the edit history, the original version wasn't nearly as good.
So my question is, would it be possible to divide the upvote points among the people who edited the post, instead of giving the points all to the OP? It would be fairer, especially in cases where it's clear the OP didn't even do most of the work. This question for instance.
