Prompted by this question. The original question is of questionable worth, but isn't something I'd immediately dismiss. The asker then edited it to answer the question, thus destroying the question. But I'd like to generalize this to future questions:
What if someone posts a question, then edits it to effectively destroy the question by replacing it with an answer, and yet the question itself and the edits themselves aren't inherently bad, just misplaced. In a situation like this, what's the appropriate action to take?
- Vote to close? It doesn't really seem to fit the closing options: "duplicate of...", "off-topic because...", "unclear what you're asking", "too broad", or "primarily opinion-based".
- Flag it? As what? It's not spam, or offensive/abusive/hate speech, or a duplicate. The options of "it should be closed for another reason..." and "it is very low quality" seem to be the best of the given options if flagging is to be done.
- Roll back the question to its original state? And then do what with the answer? Post it as an answer? I can't (and really don't want to) take credit for that answer.
- Edit the question to include both the original question and the discovered answer? (i.e. top half of question: original question; bottom half of question: discovered answer) But then no answer is to be "accepted," which is unfortunate; it's nice when answered questions have accepted answers.
- Leave a comment and do nothing more? But then the clutter is left to exist on SO. Certainly I think a comment should be left to help educate the user, but I hate to leave the clutter too.
