The new W3C #ActivityPub Working Group is not that. Or not just that. It's a "Social Web" Working Group and includes maintenance of ActivityPub, WebSub, Activity Streams, Activity Vocabulary, MicroPub, Linked Data Notifications, Webmention, and LOLA specifications. Maintaining all these disparate specs in one WG seems like it will lead to similar results as the first time this was tried (not great). What's that saying about doing the same thing repeatedly and expecting different results? π
