And if there is no federation, then what is the benefit of using ActivityPub? That’s my biggest question by far.

Using ActivityPub is an interesting twist I did not see coming. I could see myself trying this, despite my problems with Meta, especially because running social media for a church means I can’t really give up Facebook or Instagram and because people I know might actually sign up for it.

Not on Mastodon at the moment, but with the way Twitter has been heading it might be worth looking into, especially because getting on Lemmy helped me understand the Fediverse better.
