Signups to nostr can’t be limited because there’s nothing you absolutely have to sign up for to use it. You only need to sign and publish a note and BOOM you’re using nostr and anyone can read it. All the additional stuff like media hosting, NIP-05 registration, etc., enhances the experience but you can still publish using nostr without any of that.

Maybe we should stop calling it sign ups and just lean into the nerdiness of cryptography
In some ways I think it would be better, but then I also think drawing parallels to existing platforms helps it feel familiar. “Followers” is another good example though of how nostr is confusing for new users. “How many followers do I have?” Idk, how many people have your phone number or email address saved in their contacts on their phone? 😂
How?
Posts/notes are just little chunks of text cryptographically signed by your private key. Once signed, they can be broadcast to any public relay by anyone, and can be read from those relays by anyone using your public key. Client apps like Primal/Amethyst/etc., have a pretty UI to make it feel like a familiar social media experience.
