HN will down rank anything getting a lot of comments, I think votes might be factored in as well. It kills a lot of good topics and often allows astro turfing accounts to kill them.
Every time I make a comment that garners a large number of replies, moderators 'detach' it from the article, which I suppose leaves it in some Netherworld where it can only be accessed from members' profiles. I'm not sure what the point of that is.
No. I'm referring to a moderator making a statement 'this has been detached', not some misunderstanding or confusion I'm having. You can find it on my profile recently.
