OK so.... think of nostr like a strip club. Each of the poles in the club are the apps (damus, nostur, primal, etc) you can dance on any of those poles. You are always you (your nsec/npub) regardless what pole you're on.

Alby, coinos, etc are all wallets you can connect to your apps. Idk what they are in this analogy... maybe cash maybe thongs? Idk. Metaphor is falling apart...

But any of your wallets can connect to any of your apps. One wallet for all apps or one wallet for each app. Doesnt matter, up to you. You can jump from app to app. All of it lives on nostr.
