Overview
This WordPress plugin, leveraging the PubSubHubbub/WebSub protocol, enables real-time notifications for blog updates, ensuring subscribers receive instant updates. Widely recognized and utilized by services like Google Alerts, the plugin routes subscription requests through hubs that validate them and subsequently distribute new content upon availability. It supports multi-user installations, various hubs, and all WordPress feed formats beyond just ATOM and RSS2. The plugin adheres to the latest specifications, including PubSubHubbub Version 0.4 and W3C WebSub Version. It automatically announces active hubs by adding link declarations to your template header and Atom feed, and by default, it pings hubs such as Google's Demo Hub, SuperFeedr, and WebSubHub. Users can also request to add their own hubs as default options.
