The model of Reddit as a multistory building with a basement is flawed from the outset. It's more like a building in n-dimensional hyperspace. No matter what room you're in, the doors that lead to every other room, as well as to the street outside, are never more than a footstep away.
The same is true of the Web as a whole, at least until we allow governments and other special interests to start nailing various doors shut.
