Thanks for posting. Nudged me to reread the ActivityPub docs. Sorry, but I'm struggling to grok these decentralized social networking protocols. As in Why? (I'm having JXTA flashbacks.) By analogy, I now imagine these are public ad-hoc listservs. With some karma system features. That'd be cool, I guess. To be a pull system (selectively forwarding stuff), it definitely requires a lot of backend work. My starting point for this stuff is FidoNet & RelayNet for server-to-server push (store and forward) and QWK offline mail reader for server-to-client pull. FidoNet and RelayNet supported direct messages (email). Offline mail readers had neat features like twit filters. More of an unfollow than follow. Does the online world need karma? Omitting those use cases keeps things simple. Ad hoc listservs would be cool. I'd have to go back and check, but surely something like FidoNet & RelayNet could support that. The elephant in the room is spam. How does one prevent being overrun, like UUNET was? Spam filters, fraud detection, moderation, etc?
