@dansup Once it's fully documented, partial interop through Bridgy Fed could also be possible, seeing as how ATProto controls are a subset of what Pixelfed will support (though, if I'm not mistaken it would require Bridgy Fed to implement synchronised follower collections).
It's not a perfect match due to architecture differences, and I have my issues with the ATProto model, but overall I think it would be healthy to make small-fediverse content available there in as high fidelity as possible.
