Here is an example of a recent suggested edit to a poor question that had just been closed. The user editing the question is not the user who asked the question, and doesn't appear to be editing it in order to put it in the reopen queue. Generally, I like the idea of encouraging (and approving) even small edits that could improve a post, but this particular kind of edit (small edit to a still poor question) has come across the review queue quite a lot lately.
My perspective: the edit does slightly improve the question, but it also bumps it and puts it in the reopen queue, without addressing the problems in the substance of the question. So, while it slightly improves the question, it does the opposite to the site in general (makes it slightly worse). I rejected the edit, and left a comment to that effect, in part hoping to discourage this behavior. What do we think, should we approve edits like this, or reject them.
EDIT: On further review (and after a large volume of edits by the same user in a short period of time), it seems that, in addition to bumping poor questions, a number of these edits introduce new errors.
