http://tinypic.com/view.php?pic=scw684&s=7That's a pretty healthy mixture if you ask me. Only about 10-15% or the articles are unworthy of HN, and even that's debatable. The majority is technical stuff, with a few valuable pieces on business/economics in general sprinkled in.
So although some people seem to think the quality of comments is declining, I still believe HN provides phenomenal quality in its capacity as 'news for hackers.'
I'm not sure if changing the rules will do much good; it might have the opposite effect. I think there's pro-active measures we can take which might prove best, like: finding interesting people and inviting them to HN. Quora would be a good recruitment ground.
One last point, I think the role of the founder/leader is very important to online communities. I've been in other forums which went to absolute shit once the 'pg-equivalent-person' ditched them in favour of Twitter. More essays from Paul Graham, perhaps ones talking about online behaviour/ethos, would be a big benefit :-)
