I've wondered how HN would change if it added topic-identifying tags or "flair" next to headlines on the front page. Downside: it's adds one more bit of extraneous information to process through. Upside: It would do what all tags do: give you a way to quickly find more related articles on the same topic. (Or warn you if it's a topic you're not interested in.) But one feature that would really make tags more powerful: adding the ability to pre-filter out tags that you know, in advance, you're not going to be interested in.
