If I understand correctly, ActivityPub implementation on Lemmy is just starting and is mostly dormant (which isn’t a dig on any of the developers since no one is getting paid to implement it). But is this because it’s hard to implement? Lack of knowledge? Or simply that no one has had the time to actually start implementing it? When we do get started, how big a project is it expected to be?
I’m using these excuses (like your questions) to do a brain dump of some of the ideas I have in my head about federated link aggregators for a future blog post about it which hopefully be a bit more coherent.
