I definitely don't think it's necessary, but it can be fun. @ChadF and 33 others even suggests adding npubs to RSS feeds for social interaction. There's been some incredible talent discovered through Nostr that have embraced DeMu, and I think all of those artists benefit from the peer-to-peer interaction and opportunities to be interviewed by the writers here or podcast hosts. Plus some of them came into it knowing nothing about Bitcoin but craving a censorship-resistant social media like @Matt Finlay -- and now he's out here building a node! It's been a faster no-coiner to coiner pipeline than interacting with local businesses or people adjacent to our local meetups.
