*W3 Quote:* "The ActivityPub protocol is a decentralized social networking protocol. It provides a client to server API for creating, updating and deleting content, as well as a federated server to server API for delivering notifications and content."
*Shlee:* "ActivityPub is the idea of splitting online services into tiny self hosted pieces - Turning privately owned services like twitter into thousands of little twitters, who are able to communicate with each other as you would expect - Giving power and control back to the many."
> Alice is on Server A. Bob is on Server B. Alice sends a message to Bob. Server A sends the message to Server B. Bob gets notified of the message. :star:
