Particular to this thread, new user Manish couldn't comment due to his low reputation, but he had something to say about the question. So he posted an Answer like a comment.
Moderation: Generically the Answer is to be flagged as "Not Answer". But to the scenario and the situation, the comment-like Answer was necessary. What should we people do then? We know it's not an Answer.
Do we vote for a poll saying Open commenting to all reputed user?
Or, Do we add a comment on behalf of the New User?
