The only active onboarding happens via bitcointwitter too (primal).

As a thought experiment I see it a bit like this: would you join a decentralised social protocol (let's say it has the same characteristics as nostr) if it was ran by Ethereum or solana people. Eth or sol wouldn't be integral to the protocol however the vast majority of people using the protocol talk about Eth/sol, especially when the assets changes price.

I very much doubt most people here would tbh
