PubSubHubbub - Wikipedia
"PubSubHubbub is an open protocol for distributed publish/subscribe communication on the Internet. Initially designed to extend the Atom (and RSS) protocols for data feeds, the protocol can be applied to any data type (e.g. HTML, text, pictures, audio, video) as long as it is accessible via HTTP. Its main purpose is to provide real-time notifications of changes, which improves upon the typical situation where a client periodically polls the feed server at some arbitrary interval. In this way, PubSubHubbub provides pushed HTTP notifications without requiring clients to spend resources on polling for changes.
As for April 2017, the PubSubHubbub protocol has been adopted by the W3C has a Candidate Recommendation and renamed to WebSub for simplicity and clarity."

Mastodon Is What Disruption Looks Like Right Before It Happens
mastodon.social - Mastodon
"Mastodon is a free, open-source social network. A decentralized alternative to commercial platforms, it avoids the risks of a single company monopolizing your communication. Pick a server that you trust — whichever you choose, you can interact with everyone else. Anyone can run their own Mastodon instance and participate in the social network seamlessly."
