I'm taking about this answer which is essentially pedantry about two variable names, which seems to be meant as a funny remark.
I mentioned (in the first comment) that such an answer contributes far less than the other answers, even though variables names are important, especially for the code's future maintainer; yet, the community upvotes it to the #2 answer. I don't particularly care about that, but rather the fact that the answer would be much better suited as a comment.
Should this kind of pedantry be discouraged? Does it really contribute much to the Q/A as an answer, and should such answers really be comments?
