Before the fediverse becomes normalized for non-technical people, the tech jargon will have to be changed. Anytime a non-technical person hears server, instance, node, etc they glaze over in the eyes. These should be called something like communities or groups or clubs or something to tell people they are joining a group of like minded individuals.

After that, I do like the way kbin has used the magazine concept of magazine, article, post, microblog to describe the methods of communication within the "community". Even though admittingly, it took me minute to grasp the jargon change.

The selling point is federation, but that name has to go, too. Sounds to techie or bureaucratic. I don't know Connecting or something. Users need to understand that from their community, they can connect to (and interact with) other communities or members without having to join a whole new site. In that same sense, they can also block any community or member they do not wish to interact with.

Another selling point would be that if a community changes and you do not like it, you can just join a new one. However, this is not really a selling point yet because you cannot just mover your "profile" to another community. You have to rejoin and start from scratch.
