Better moderation of the blog spammers may help as well. For instance: http://news.ycombinator.com/submitted?id=ccraigIW http://news.ycombinator.com/submitted?id=ccraigIW has 11 submissions in the past 24 hours, none with a score > 2. That's a third of the "new" page filled up with blog posts from one source. Karma threshold, average submission score or signal-to-noise ratio may be a good way to rate limit submissions.
