It’s true a comm made on any instance can be accessed from any other instance on the network.

But in addition to personal preference and just wanting to keep things neat, it also helps keep things more decentralized to help prevent one instance becoming too big for its own good. Aka the .world problem

Lol I make them as I need them, .zip is a “Gaming and tech focused instance” so now when I make a comm that falls into one of those categories I’ll make them here
