I have an automated filter site at http://hacker-newspaper.gilesb.com/ -- "don't click on what doesn't interest you" is way inferior to "don't see what doesn't interest you."
Your filters will always turn up some things you want to just like they'll always filter some things you wish they wouldn't. You'll have to live with that degraded experience the rest of us have and not click on those things. Bellyaching about unsolvable problems is just lowering the sites signal to noise ratio unnecessarily.
I think I've also figured out a pretty cool product idea from this as well. However I'm not going to get into it here because people have taken my product ideas and turned them into products twice now (actually one of them was a Hacker Newspaper iOS app which looks very, very, very similar to my http://hacker-newspaper.gilesb.com/).
In terms of what I want, well, any ideas on how to improve signal/noise on HN, whether via automated filtering or some other method.
