Nostr is for everyone. I am a rabid Bitcoin Maix and I'll never use Ethereum, however what kind of asshole would I be if I said the Ethereum community doesn't deserve to take control of their identity, attention, and content? I want you to build the best social client for Ethereum users. I won't use it, most Bitcoiners here won't use it, but that's fine, because you're not building for us. You're building for YOUR community and that's fucking cool.
