Through HN I have learnt that sophisticated discussion with a large number of participants is achievable. Which, up until this point, is something that I didn't really consider to be possible. Certainly not over a long term. Moreover the site doesn't require an oppressive method of control to keep the conversation in line. It is as much the communities common virtue as it is the technical merits of pg's system which brings that about.
