Pretty clear from the #FOSDEM #SocialWeb devroom talks that the limited set of #ActivityPub actors that Mastodon will accept is a problem for almost every other platform.
That’s not Mastodon’s *fault*, really, but it’s just a factor of being the dominant platform; it pushes the interoperability problems out onto others.
@Floppy I hope some one can write about that as I only sort of understand! But seems like more would care if they understood the limitations!
