It's the underlying protocol that connects the various federated services in the "Fediverse", (see https://en.wikipedia.org/wiki/Fediverse) like Mastodon, PeerTube, NextCloud, etc. At root it's just a standardized way for nodes in a network to send messages to each other, though, so you could use it to get those "connections of a social network" you're looking for. And then Mastodon users, say, could get updates/notifications from your site/service/whatever right in their feed.
My first website was about about TNG and why DS9 sucked balls.
Ironic since I now consider DS9 the better series (but TNG still has the truly stand out episodes, I think young me was just oblivious to a lot of the subtler stuff but I digress), it was shockingly bad (and I'd been programming since the 80's, HTML was just weird).
I spent about five years hating the crap out of it and never even considered web development as a career, if you'd have asked me back then I'd have said you'd claw the compiler out of my cold dead hands.
20 odd-years later and I do enterprise web dev (and C#/WPF and Java)

Trying to shoehorn social media profile integration into this system will eventually end up influencing the content, and once more it'll be a race to the bottom, with everyone posting stuff only for other people's validation. It shouldn't work that way for the 'weird web'.
