Don’t you mean a quarter of the footprint? It’s half the size per side.

Personally I feel the entire point is it should be done like that. Like it was in the 90s. Every little cats community can be out there and independent from each other; communities, identities and administration can remain separate. For discoverability, rather than make it part of the platform which would eventually induce dark incentives towards the kind of consolidation that happened with Reddit in the first place, well, why not also do it like back in the 90s? There used to be the webdirectories, as well as the webrings (in Yahoo, Geocities, etc) that served as an independent discovery system.
