I keep asking this, but it never gets much attention - but why can't reddit put more effort in to a hierarchical structure. As others have said some of the best contents is in the smaller sub-reddits, but they often struggle to get much content because people feel that to get any "attention" they have to post in a sub-reddit. I feel people would be encouraged to submit to smaller sub-reddits if there was a hierarchical structure whereby if a story did well in a sub-reddit, it would get to the front page of the next sub-reddit above it - so I might submit to /r/Dundee which leads to /r/Scotland which leans to /r/UnitedKingdom etc I'm sure there would be some clever way to structure and control this. It would breathe life in to the smaller sub-reddits.
