the topical territories are good for this:

you can set up notifications and just read those.

side note: @ek @k00b I think there's a use case for a different "notification" scheme that just shows posts in subscribed territories separately from post notifications... different from reddit, but still an alright option given relatively lower volume of posts. I can make an issue for this design idea so folks can bicker about how to do it, I'm only just now putting thought to keyboard.
