Network effect is a relative thing. MySpace had a bigger network effect than Facebook until it didn't.

But is it really Nostr vs Twitter or is it more about Amethyst/Damus/Nostrgram/etc vs Twitter? Nostr's "just" the protocol, right? The user experience is in the clients on top.

Seems like the more direct competition for Nostr is Bluesky's AT protocol. Or am I wrong there?
