The ownership part sounds exciting to me as well, this is the first time I’ve heard about a coop. You also raise a valid point about it being open source. I just don’t really see it becoming as popular as bandcamp or Spotify, since for a regular consumer (who doesn’t like to hop platforms) I don’t think the features could be warranting a switch. I’ll definitely will keep an eye on this project though, I hope it takes off!
Any alternatives to google docs/sheets? It’s really convenient for shared documents, and it’s the only thing (other than gmail) keeping me in the Google ecosystem
