better yet, get rid of the comments all together. having no comments saves you from having to moderate them and it's just not worth it. if you're writing anything tech related and worthwhile you can just proxy the discussion to HN ;)

Not really a great option. People only really see stuff on HN that's relatively fresh so anyone coming in after the initial wave of engagement dies down won't see any discussion.

Also you can't discuss on old content anyway. It's blocked.

Yeah, somewhere around 2 weeks after a post they completely seal the comments on HN.
