I made it over a huge hump with implementing #ActivityPub in #LittleLibrary by looking at @pixelfed's source code! I pretty much just need to make sure new additions send updates to followers and then it'll be ready for testing.
It'll probably be the Most Minimal production AP implementation, only allowing followers and nothing else, and I think that's pretty neat.
@Alamantus same here, I only implemented follows and it's working nicely. 🙂
For many use cases you don't need more.
