I like the idea of having a single thread for all related stories. That way if a particular story was generating a lot of noise it would just be one line on the front page and very easy to ignore. It would be a bit like subreddits but more dynamic, the subreddits would flit in and out of existence. Everone would still share the same front page, perhaps each line would be something like "NSA: latest story headline". The question is, what would be the best way to do the grouping?
