What do you think about promoting an answer via a comment on the question? I have seen this a few times, but just came across: Python Remove last 3 characters of a string
noctis's answer is best. just saying.
We could assume that the comment was written because the accepted answer is not the most upvoted, and they are hoping to get the user to accept the other answer. However, my understanding is that the recommended approach is to leave a comment on the accepted answer, pointing out any issues and mentioning the preferred answer.
While it is benevolent, the author doesn't try to justify the comment at all. Would you flag this comment? And, regardless of the example, what are your thoughts on promoting answers this way?
