In light of the discussion here (verdict: NAA is not to be used for "Answers a different question") and here, the NAA flag seems a bit redundant and ambiguous to me. AFAICT, the current legitimate uses are:
- Is a separate question
- Is meant to be a comment
- Is just random text that obviously doesn't answer the question (e.g. "Bubblegum")
- Is a link only answer
To me, points 1,2,3 are perfectly covered by VLQ:
This answer has severe formatting or content problems. This answer is unlikely to be salvageable through editing, and might need to be removed.
All three are unsalvageable. And they have content problems.
Point 4 is better served with a custom flag (though NAA is OK too), as detailed in answers here.
With this in mind, do we really need the NAA flag? The wording "does not answer the question" is rather ambiguous (Does a link-only answer count as "answering the question"? How about "an answer to a similar, but different question?"). We have discussions on meta clarifying these, but the average flagger doesn't know about them. I myself can't think of any concise flag reason that makes this clear.
So, can anyone think of a more accurate flag description for NAA?
If not, is there anything wrong with just removing the NAA flag?
