I was wondering, why shouldn't edits get a small bit of rep for an upvote? (Like 1 rep for upvoted question 2 for upvoted answer) Because I answered pretty badly, but someone (fabby) edited it and it was SO much better. Maybe some of the rep should go to him as well on an upvote. We could scrap the 2 rep per edit if we do that, but does anyone have any reasons why or why not we should have this? Also we could have a downvote taking away some rep too.
I think you get the wrong idea of what actually is the function of an edit.
An edit should contribute to the clarity of a post. A good edit may also clarify that the question is a bad one. Sharing in the possibly bad response (implicitly also what you suggest) would be the opposite of what is reasonable, and the opposite of what we want.
Your suggestion would have terrible side-effects: greedy editors might jump on questions that are already good to begin with, hoping to share in their success, and giving reviewers more work to filter out silly edits. At the same time, it is the not-so-obviously successful posts that need good edits to make sure it is valued on the content
For acceptable edits, users below 2k get 2 points reputation, to encourage editing by new users. I think making the effort for good edits is what we may expect from experienced users anyway.
