I've toyed with the idea of having a standardized and decentralized social network that would work much like how SMTP (or XMPP) does today, in that each domain could have it's own set of social media servers, controlled via SRV records, and data is propagated and cached on-demand between domains that socialize with each other. Obviously, great care would need to be taken to ensure the Internet isn't just flooded with a bunch of traffic all the time (see: intelligent caching solutions). This way, no single commercial entity is able to control and manipulate it to their own advantage to the detriment of its users.
Combined with the in-development ActivityPub gateway from Libervia ( https://salut-a-toi.org/blog/view/goffi@goffi.org/@/id/liber... ), interop with Mastodon, Pleroma and others becomes possible too. The decentralized social web space is quite active at the moment.
