I posted this yesterday on Nostr. I think it fits as a reply here.

I see many notes worrying that Nostr isn't growing fast enough. I'm not worried though. I don't think the growth will be linear.

All it will take is ONE application to go viral. The day that happens the whole thing will explode. That's the protocols magic. Once people get sucked in, they can already "log in" to every other thing made on Nostr. That's the day every Nostr apps user count goes to the moon.
