I wonder if you are maybe too close to the problem to see it from a normal HN user's perspective. From my perspective, I don't get this impression because I don't see the full breath of conversations that happen on HN like you do. People clearly want to talk about this here and I have rarely seen these stories actually on the front page of HN because they are so quick to drop off the front page due to flagging, downvoting, the flame war detector, or whatever other behind the scenes mechanics exist that you are obviously more knowledgeable about than me. People continuing to have conversations on posts that no one sees unless they specifically search them out is the equivalent of shadowbanning those conversations. Yes, they are still happening, but the normal HN user isn't actually seeing them and that is why you are fielding so many complaints from normal users who want to see these posts.
