Macrocommunities

Looking through the communities, wouldn't it be nice if there was a collections of communities for newcomers, a community that you can't post to, but shows only posts from other communities related to it.
For example b/monaco (b for bigdigg) would contain the posts of the following:
/monaco
/monacoTravel

/microstates
/monaco_food
/monegasque
/Casino_Monaco
/cinemaofmonaco
but people could not make threads about it, mods of each of the above could also opt-out of joining b/monaco, and anytime a community is made about monaco, it could prompt the creator to add it to b/monaco.


Just a thought. Would probably be a pain to code though...
