I agree with the premise, but believe the author cites the wrong reasons. What happens to online communities over time is the same that happens in any social organization. A few, more aggressive and hardcore members gain the power to snuff out dissenting viewpoints and opinions, thus overwriting any chance for diversity or originality. To make matters worse, those that use downvoting systems wind up alienating new users that can't seem to figure out the "game." Those without voting systems use humor, belittlement, and castigation to do the same. In the end, the scene is controlled by those holding a majority opinion, and any objectionable opinion is pushed out. This happens in any community, whether it's your local church, a football forum, or a place like HN. Where they fail in terms of diversity, they succeed for the group that holds the power.
