I like tags more than subreddits, because you can have several tags on a post, adding new tags doesn’t fragment the audience, and you can add tags to existing content retroactively. MathOverflow is a good example of a site where you can follow tags as if they were subreddits. Maybe we just need to make tags more prominent on LW, e.g. have a list of tags as the main navigation, and make them mandatory for new posts?
Also, seconding the suggestion that posts should be promoted to Main from Discussion, not directly posted to Main.
