I have noticed answers that I see are either blatantly wrong or low quality but I know those shouldn't necessarily be flagged (for "not an answer" atleast). Then there are answers that I have flagged because they really weren't answers but rather discussions.
This leads to my current question, what about answers that seem to fall in the grey area between comments and answers? It potentially could solve the OP's problem, though not exactly the question.
An example I just came upon is this: http://stackoverflow.com/a/11121343/938695 I am going to go ahead and flag it as "not an answer" but I wanted some feedback for future predicaments.
