Stackoverflow may be the only site where I ever use tags. Tags are useful there for finding questions you can answer. You can watch tags of topics that you probably can reply to and browser the front page with a collection of interesting questions. Or look up the new questions page of a specific tag. The same could probably done with search terms saved to your profile, but the tags are a much more organized alternative.
