Nostr doesn't need to be mentioned anywhere forefront in a client to be successful. How deep in Settings do you need to go in Gmail to see POP3, SMTP, or IMAP?

I love Nostr, but there's 8 billion people out there that will just use Nostr, just like they use the web or email, and know NOTHING about the underlying protocol.

And that's how it should be. Technology works best when it fades into the background.
