Sadly, but the whole buzz about social networks is built around the community. And any of federated networks require some technical knowledge that is over the head in 99% of regular users.
I wish this could be a bit more user-friendly, like p2p networking that does not require any user configuration, just install a client and it will p2p automatically.
P2P? I have a p2p social network with a public/demo instance hosted at https://rostra.me .
More importantly I feel like federation is a reaction to a problem small social networks don’t have.
I want a Tumblr for just people I know. I don’t want it to metastasize and interact in any way with people I don’t know.
