This is just a random thought but I was wondering if recursive communities would be useful?

What I mean is this: say you have a community for car stuff: /c/cars

And you want to have a community for Asian import cars versus another community for offroading. You could make /c/offroading and /c/importscars but you could also hypothetically organize it with /c/cars/offroading and /c/cars/importcars

I don’t know if this would actually be worth doing at all. It’s just something I’ve thought about for years with reddit. It’s also I think kind of how usenet worked?
