I have no problems imagining a different timeline, where #ActivityPub had been already a better-established thing, and the demo #OperaUnite applications for media and photo sharing had implemented basic support for it, resulting in self-hosted lightweight alternatives to #PixelFed or #FunkWhale.
And this is actually the vision I have an ultimate goal for the #Fediverse, one where, thanks also to client support, hosting and participation become even more trivial than setting up a static website.
