I’d like to add that @mathewlowry’s post made me spin off into this: What is the Vision of the Fediverse?
It’s fully understandable and logical that the fediverse started to explore better alternatives to traditional social media first, once they got the AS/AP standards in their hands. Now there’s the opportunity to a) go well beyond that and address the social aspects in many different app / business domains, and b) to come to a much deeper level of integration between individuals apps, and maybe even to such extent that ‘app boundaries’ disappear. The latter is what in the past I called From silo-first to task-oriented federated app design.
