I recently asked the question Problem with Compiling .pdf. Clearly, it has been put on hold, and reasonably so given the close reason at the time it was closed. Now, there is a new answer that renders the reason it was closed a bit inaccurate. As the OP, should I delete the question? Or should the question be reopened?
I would think the community's voting behaviour should speak for itself in judging which of the two answers are valid/useful. Additionally, if you feel that the second answer is "not useful", vote accordingly.
Finally, consider the community. Does the post in its current form serve a broader audience? If at all, it's worth keeping.
