@nostr:npub1cmgqvz7xr07euwkum3mjghjqcu4d3k2fcyf6g4uwwe5ggnd6fetq0wrzd2 Is Mastodon a service? I think it is a software. The "service" is mementomori.social and many others, some of them not being a service at all. It would be better called Activitypub provider network, technically speaking, or Fediverse, which is wider term and covers other protocols too.
