Am I misunderstanding, or is ActivityPub just reinventing RSS?
Activity Pub is much more flexible, the tradeoff being that it’s more complex. ActivityPub is basically a flexible CRUD API specifically designed for social networking, with support for federation.
You could fulfill the purpose of RSS with ActivityPub. But, it doesn’t supercede RSS/atom, because the simplicity is valuable for the cases those protocols handle.
Had the same thought a few days ago when I discovered Podcast worked with RSS and that you could get Podcast and News technically in one place
Awesome, I’m not sure what substacks is but ghost is pretty cool and I like to federate
Adding to the Nazi comment - substack is basically a long form blog format, very similar (AFAICT) to Medium.
Substack is just another platform where the nazis run wild thanks to capitalism or misguided ideas of what free speech is supposed to mean.
I have been working on a personal Ghost blog and this is amazing news for me!! Ghost is a joy to use. I am curious about the performance requirements, how it will work with self hosted, I have mine on a cheap VPS.
