I saw a new edit pending approval in the edit toolbar this morning, and was about to reject the edit when I noticed it had already been approved:
The problem with approving this edit is that the question itself had problems that really needed addressing:
So now we have an editor that made an edit that didn't really help anything, and we reinforce this behavior by approving it.
Luckily, someone else came in and made the edit that needed to be made, but I have to ask, aren't we just causing ourselves extra work by approving edits that don't actually improve the question substantially?
