A number of these coincide with existing territories. Health and fitness, ask SN, agora, movies, oracle, education etc.

And I think a number could exist as sub territories. Chess could be part of gaming or sports for instance. I always liked the idea of not waiting for sub territories and just creating pseudo ones. For instance, @needcreations could bring back Chess and just put all the posts in gaming or sports with a Chess specific label and then the territory owner can share some of the revenue with them. It drives more attention and a broader audience to the territory earning the owner more revenue and saves the sub territory creator the cost of rent. Maybe there could be some small rent from the sub to the main territory like 5k sats a month and then they share the revenue those posts bring in.
