I don’t need any new Slack-like things, but Buzz is actually pretty interesting. It’s built on a Nostr relay and has a whole page about domain names and identity:
myproject.com is your workspace. Not a GitHub org page that happens to have your name on it. Not a Discord server that Discord could delete tomorrow. Your domain. Your relay. One thing.
I’m getting a little maybe written by AI vibe from some of the docs… But regardless, it makes a good (if verbose) case for the architecture.
