I was recently reviewing in the Low Quality Posts queue on Stack Overflow, and I encountered an answer that really had nothing to do with the question, but could answer a different question. The question was basically how do I get a value from a widget in framework A. The answer was how to create a widget in framework B. It is an answer. It's not necessarily wrong. But it's not related to the question.
When I encounter this sort of situation and I feel knowledgeable enough to determine that the answer, while technically an answer, does not answer the question, I "Recommend Deletion" as "This is commentary on another post, not an answer":
This does not provide an answer to the question. Once you have sufficient reputation you will be able to comment on any post; instead, provide answers that don't require clarification from the asker.
I was recently told by a higher reputation user that this is wrong because it's still an answer. I disagree, but I could be wrong. I "Recommend Deletion" (and down-vote) because I think it does not "provide an answer to the question". What is the proper procedure to handle answers unrelated to a question encountered in the Low Quality Posts review queue? Do I:
"Recommend Deletion" as "this is commentary on another post, not an answer", and down-vote?
"Recommend Deletion" with "no comment needed", and down-vote?
Reluctantly say "looks OK", and still down-vote?
Is this site specific?
NOTE: This is related to, but different from When an answer answers the wrong question, is it Not An Answer? because this deals with how to handle answers in the Low Quality Posts queue, not flagging answers as "Not An Answer" with the hopes of putting them there.
