Reddit encourages in-group domination, by way of ignoring policy-violating cross-subreddit moderation and banning; Twitter, by design, encourages user retention through passionate engagement with other users, and most often that passion is hatred. HN doesn't have a corollary for sub-reddits, or a personal feed, or similar. Its singular subject focus is its virtue; but, as you claim, it will fall. All things will, and the problem with HN is that there is _too much money to be made_ by swaying opinion on this forum.
