The big downside with Nostr is it’s not built on the web. With blogs and webmention the feeds are websites. And there’s already a huge ecosystem for blogs. I’d prefer people build on that instead. Especially if the end result is more or less the same: blogs with comments.
I first heard about nostr last in November when Twitter tried to ban it. There's an incredible dev ecosystem developing — so much so that I decided to rebuild Satellite (https://satellite.earth) the social platform I'd been working on to become a client for the protocol.
There's a bunch of other clients too. Someone started a directory here https://www.nostrapps.com/
I'm happy to answer technical questions about nostr if anyone is curious.
