When a lemmy instance federates, does it connect to one big lemmy network, or can there be multiple disconnected, yet locally federated instances? What I’d like to know is, can I simply join any Lemmy server and choose “All” to view everything Lemmy has to offer, or is there still hidden content?
I understand that some servers are unfederated. I guess I’m curious about the reach of the “All” mode.
Yes, there can be two or more networks that just about completely defederate each other. However, you can host a Lemmy instance and federate with whomever you see fit unless they block you.
