@jackmcbastard Isn't what you asking for already what !gnusocial is? I'm a bit new too... But that's what I have understood. Nodes only see other nodes they are already following, yes, one network but not necessarily all unified like you say, because it's a decentralized/distributed network. And I'm sure (I'm speculating) there is a way to make your node only visible to those you want to see you.
