Subreddits that are interesting in some way have a tendency of growing and thereby losing quality. I suppose that the fact that HN is a different site with barriers to access (slight) would limit new users to those who are really interested in the community. Add to that the strict moderation of topics (mainly by user voting) and you get a 'subreddit' that loses quality slower.
