Guess this calls for tags more than anything. I want to exclude: startups, windows 8 (wtf - why nobody complains about this?), capitalist pigs.
Follow HN (http://archfinch.com/tag/hn), block startups, (http://archfinch.com/tag/startups), windows8 (http://archfinch.com/tag/windows8), then subscribe to your personal RSS feed.
Perhaps I could make it into an extension.
