K00b mention an update to the territories that brings sub subs So it will be ~history/vikings
I still think this is a good question. There is a lot of content that might be valued on multiple subs, but the original post didn't cross post it. It would be nice if we could pay the posting fee to cross post something from one territory into another and then get some share of the zaps that come from that territory.
aah thanks I missed that 👍

from the announcement:
create territories within other territories, eg ~bitcoin/privacy and ~bitcoin/mining the territory founder can sell sub-territories to other stackers at a price of their choosing
