PubSubHubbub is now known as WebSub and is a candidate recommendation by the W3C. 🎉
WebSub provides a common mechanism for communication between publishers of any kind of Web content and their subscribers, based on HTTP web hooks. Subscription requests are relayed through hubs, which validate and verify the request. Hubs then distribute new and updated content to subscribers when it becomes available. WebSub was previously known as PubSubHubbub.
Also, this is supported by Medium on users and publication feeds!
Next steps: convince anyone implementing webhooks in their API to make it WebSub compatible… and yes, this should be fairly straightforward!
