This isn't like mastodon tho. The notes can be streamed and moved at will. Your pubkey is not tied to one instance. If you wanted to provide an alternate relay team and also cover the topic somewhere else, it's easy to just stream from the first relay and have a new relay with a different team. Members can connect to both at once.

At the end of the day, I don't really get Twitter. It seems like a fundamentally broken social paradigm to me. I hope nostr can do better, create more chat use cases, and that's where it's good to have options for relays just like we have options for clients.
