This question already has an answer here:
This is a follow-up to the question that discussed what to do when both the question and the answer are bad. My next question is what to do when the question is bad, but the answer is not.
Here is an example of one such question and answer. The question is closed as "too localized", and the answer is flagged as "not an answer". On one hand, I would agree that the answer is not definitive in any way; on the other hand, it has a decent probability of sending a reader in the right direction - after all, it helped the OP. That is why I would be hesitant to remove the answer.
What is the preferred course of action in this situation? Should I disregard the potential helpfulness and second the flag, or would it be better to dispute it?
