In the flag answer dialog we have the following option:
not an answer
This was posted as an answer, but it does not answer the question. It should possibly be an edit, a comment(*), another question, or deleted altogether.
Presumably, this(*) is the option we should use for 'noise' answers. However, it doesn't spell it out. If someone posts something terrible like "first", how are we to flag it? If it is using this answer, could "noise" be added as a qualifier for this option?
I saw a corollary post to this issue, and I'm not sure if Jeff's response will be the same, but again this is at the minimum to add 'noise' as a stated option.
(If I should just be using another option please let me know.)
