People answer questions, I offer my answer, and other people answer after me. Some of these answers, I've found, have mistaken the question or have some critical flaw. Is it proper etiquette to critique these answers (at a basic level) in their comments?
I feel bad because it might give off the impression me saying "Hey everyone, my answer is right and yours are all messed up!".
On the other hand, it would increase the quality of all answers.
