Surfacing (and using!) them in that way is how you get to their #normielization.
To the people around me (of which 90% doesn't use or enjoy Twitter btw) I show this:
Then I tell them: "Every chat/group/community you see here **is** a Relay (server)"
They all get that part straight away and thus know what relays to choose for their outbox 👉 the communities they want to publish in
They also grasp pretty quickly that they can publish more than just chat messages in there: posts, articles, events, audio, repos, ...
And honestly they get pretty exited about this part specifically.
In my designs, every such publication, when opened, displays to what communities it was targeted (and accepted of course):
This helps with community discovery and with helping them understand that they can target their stuff to more than one public community at once.
Then, for the inbox-part it comes down to shilling the benefits of having a personal relay:
- a backup of all your stuff
- fast access and computation for you specifically
- having your own inbox that you can set a price or other conditions for
- publishing private things exclusively to a whitelisted set of npubs
- privacy in general
- etc...
One last thing that can help is not displaying relays as freaking geeky looking websites 😅. Relays need npubs, and the profile name that comes with it, if you ask me.
