Let me reward a good edit on my question/answer
I love the fact that this site, and the entire SE network are very community driven, but I see a lot of people, answering questions, where multiple answers are very closely related. That's why I'm wondering about a way to encourage people to add to an already great answer using the edit feature, instead of adding their own. Maybe the possibility to vote on edits, so people who contribute to an answer can get some rep from that as well, or something like that.
What do you think would be a good way to do this?
