&gt; <i>I think it&#x27;s groupthink, extremely low quality&#x2F;uninformed discourse, and brigading. I wish that there was a site with an hn-level of moderation that covered issues like bikes, local news, etc. Maybe that&#x27;s just not possible?</i><p>It&#x27;s possible on reddit. reddit.com&#x2F;r&#x2F;AskHistorians is a Q&amp;A subreddit for asking historical questions. They have a very high standard for answers, comments, and even the questions you can ask. and they actively enforce it. As a result it&#x27;s a very high quality resource.<p>It can be done, <i>if there&#x27;s the will for strict moderation, from the mods and the users</i>.
