I think user generated tags go a long way in filtering out which stories I'd like to read/explore. (I used to read Slashdot until I found HN a few weeks ago). For now I just use the number of comments as good first approximation.

I think these tags would be useful:

[programming] [startups] [drama] [meta]

It wouldn't be that hard to make an auto-tagging userscript using Delicious.
