  • $\begingroup$ I've copied these comments as a community wiki answer because they are, more or less, answers to this question. We have a dramatic gap between answers and questions. At least part of the problem is that some questions are answered in comments: if comments which answered the question were answers instead, we would have fewer unanswered questions. $\endgroup$ – mkt - Reinstate Monica Jun 20 '19 at 12:59
  • $\begingroup$ So, if the answer is simple enough that a comment can do the job, what's the big deal? Also, part of the reason why people use comments is that one-line answers often get dozens of downvotes $\endgroup$ – David Jun 20 '19 at 13:10
  • $\begingroup$ The fact that four people have talked about it on Meta does not mean that the average user cares. Also, I am pretty sure that if those correct ansewrs were indeed posted an aswers, they would be downvoted $\endgroup$ – David Jun 20 '19 at 13:53

    $\begingroup$ @David If a question is answered in the comments, that question clogs up a pipeline of unanswered questions. People seeking to address genuinely unanswered questions (as I was, when I opened this question) would waste less of their time. Also, answers that are incorrect could be downvoted (which cannot be done for comments), thereby sending a clearer signal of how useful it is to a new user enocountering it. $\endgroup$ – mkt - Reinstate Monica Jun 20 '19 at 14:00
