Let me reward a good edit on my question/answer
What if the author of the post could approve the editions by upvotes? With, possibly, a hidden comment?
It could work instead of "thanks for edition" in the thematic comments and make them more readable.
Later, for collecting, say, 30, 200, or 1000 of such thanks, the editor could get badges for it:
Accepted Editor, Valued editor, Favorite editor.
