Why is Nostr quite unpopular in the open source space? I was at the FOSDEM conference and everyone was talking about Matrix, which is nowhere near Nostr in terms of polishness (in my opinion). I am not sure that people even knew Nostr there.
Bitcoin and politics I'd say, I spend a lot of time on the Fediverse and no one says anything positive about the broader crypto scene, with good reason, most of it has been scams. Nostr users tend more toward right wing Libertarian view points, Fediverse is more left.
Matrix is great - we've been using it as a slack / teams / discord dropin replacement for years Our instance is open for others - https://chat.nostrdev.com
I need to take a second look then!
