@john @admin Yes, but also the great thing about standards is there’s so many to choose from, and in theory Mastodon could support IndieWeb in addition to ActivityPub. Having multiple subscription types (and support for bearer tokens and adaptive polling) wouldn’t be the worst thing.
IMO the most unfortunate things about Mastodon’s implementation from a UX standpoint are their assumptions about post formatting, and their insistence on Webfinger as sole form of identity.
