It is common to criticize certain comments as ‘unhelpful’. This criticism is richer than it might first appear. In this paper, I sketch an account of conversational helpfulness and unhelpfulness, the reasons why they matter, and the utility of calling out comments as helpful or unhelpful. First, some unhelpful comments are or easily could be demoralizing for proponents of projects, and criticizing them as such can diminish, deflect, or defend against that demoralization. Second, some unhelpful comments redirect or derail conversations (...) away from their projects and criticizing comments as unhelpful can steer conversations back. Third, some unhelpful comments are made out of a lack of epistemic effort and criticizing them as such can help maintain epistemic standards, standards of respect for other people and their projects, and can ensure that such comments do not receive more attention and consideration than they deserve.
