I wrote an article for the Mozilla Hacks blog that's a brief technical introduction to ActivityPub. I also provide an intro to my simple #ActivityPub Node.js server.
@darius nice, u know why the working group close? I feel, there is so much more to do.
@Transflux I don't know, perhaps because the point was to publish the spec. There is a community group in its place.
@darius oh I didn't find that, just a silent Google group... quite ironic actually
@darius this chat is quasi private, no?
