I hope this phenomenon is not limited to HN, but this is the only place I'm aware of where the comments are often more interesting and useful than the posts.
I'm addicted to HN comments in a way that's almost certainly bad for me. I skim the articles (if that) and then hop into the comments section to pontificate about whatever topic is marginally related to the article I didn't read. Maybe my attention span has entirely eroded, or maybe I lack an outlet for the never-ending torrent of racing thoughts that keeps me up at night. But either way, here we are.
