People make their choices when they participate in HN comment streams. As far as I can tell, there is no RSS feed for comments here and there is no advanced way of keeping track on commenting. You have to manually browse to participate yourself into the conversations. Over the few years, HN has sort of become the Digg and Reddit. There are far and few substantial conversations in visible view (yes count mine as unsubstantial as well). From the logical perspective, the circle of HN needs to break off from its core and diverge into many different circles. There may already be few inner circles (hidden from the public view) I can't tell. But it seems logical that this big public circle is all inclusive, where everything goes.
