One of the few things that I like about HN is that when someone responds to your comment you are not necessarily supposed to reply to that, definitely not the only one. I don't think it is by design, but anyhow it has come to be as such. Sometimes you don't even have to respond, or anyone for that matter. Not having a notification system adds in this. PS. Visible karma system is one of the worst things on HN and among many that I don't like. It has no place to be here. At the very least it ought not to be exposed on profiles and comments.
