Five years ago (Monday the 23rd) the @W3C Social Web Working Group published the WebSub Recommendation^1

The test suites https://websub.rocks/ for Publishers, Subscribers, and Hubs are still up & running, as are the vast majority of implementations documented in the implementation report.

My site supports the publishing side of WebSub via the Superfeedr Hub^2 and there are many more supporting sites^3.

Beyond publishing blog posts and realtime updates in social readers^4, there are additional WebSub use-cases such as real time #IndieWeb search^5 results, like Technorati except opt-in via WebSub subscriptions, and without any polling.

Such diverse use-cases are one of the benefits of building-block^6 standards^7 like WebSub.

If you create a new WebSub implementation, be sure to test it with the test suite^8 and add your results to the WebSub Implementation Reports repo^9.
