Just used nostr with nostr console and it was quite nice. Feels a lot like Usenet. The lightness of the protocol makes it pretty powerful, though I wonder how spam will play out. I don't really see the same benefits of running a relay like I do with a Mastodon instance. I kinda like the ownership aspect. Other than altruistic reasons, what motivation would someone have to pay for a nostr relay that everyone else takes advantage of?
