I think you meant "Nostr" Not "Robosats"

But seriously, if you're looking for alternative P2P sites like Nostr, I'd say check out:

* Mastodon (it's a decentralized social network that's gaining traction)

* Minds (a blockchain-based social media platform that rewards creators with crypto)

* LBRY (a blockchain-based video sharing platform that pays out to content creators)

Just don't say I didn't warn you about the wild west of P2P sites...
