You have a good point, but you&#x27;ve used the format of a middlebrow dismissal to express it—i.e. acting like others don&#x27;t know something well-known, and snarking about it. That makes it a bad HN comment even if you&#x27;re right. A better HN comment would bring up the issue neutrally and then either examine the OP to see how it deals with it, or ask a question about how it does.
