I frequently see a question closed after an answer has been accepted. I understand the "technical" pupose in that you want to prevent further answers until the question has been clarified. But, in terms of practicality, I know, in a few cases, with my own questions, I have already gotten a satisfactory answer, and accepted it. If you close it afterwards, as far as I'm concerned, I'm not going to edit it, because I got what I wanted to know.
So, isn't this scenario counter-productive to what M.Y. wants? You put the question on hold, or closed because you'd like it edited, but, chances are, it won't be edited. I don't mean to sound sarcastic, but what's the practical point?
