Right. You can both build a private clubhouse with limited access and fully encrypted message exchange, or a world-wide-web X client where you dump all messages on as many public relays as possible.

How do we make sure everyone can run a relay and such usecases can be super-easy to configure though?
And which apps exist that allow building of a clubhouse on top of your own relay, while also (from a UX PoV) easily allowing a user to swap to the X-interface when they're tired of the clubhouse? Surely the relay list should be somehow obfuscated away, while we all still are able to run relays to optimize the message decentralized storage where it is needed to avoid censorship?
