Edits on Super User are very important, it gives sense to many questions and answers here and I think it deserves a good stimulus (such as "Editor" and "Copy Editor" badges), but in my humble opinion it also deserves a counterpart. I mean, if you made a bad edit, you should be "penalized" and receive feedback from moderators and the community to help you improve your edits.
Most edits are good, most of them are useless and some just scratch question/answer sense. My suggestion is a system that, similar to how questions/answers can receive up or down votes, lets users vote on edits.
I'm not speaking about giving reputation to edits, but there could be, for example, another Gold/Silver/Bronze badge for +500/+200/+15 "upvotes" on edits. Each edit "upvote" would sum up to have users reach the badge – and each edit "downvote" would decrease this sum.
This is just an idea that I would like to discuss and to make people think about, feel free to edit/improve anything here.
PS: I already made a lot of "bad" edits but nowadays I have acquired experience to improve my edits just like I got experience in writing better answers and questions than maybe one year ago – this all was stimulated by the reputation system. What I'm thinking here is to provide to new users a way to encourage good edits and, in consequence, better answers and questions on Super User.
