True that most of the conversation on Nostr is about two main topics:

1. building Nostr

2. Bitcoin

That’s because Nostr was built by Bitcoiners who passionately believe in what they are doing.

For what it’s worth, Nostr has far more potential than mastodon as a truly decentralized network. And the Nostr platforms like Damus and Primal seem to have passed Mastadon in UX design. At least since the last time I looked at Mastadon anything a couple of years ago.
