Implements a Pubsubhubbub Real Time Publisher informing Planet Earth of your updates now, not later!
Implements the Pubsubhubbub protocol based on the current PubSubHubbub Core 0.1 Specification and any changes since its publication. PubSubHubbub is an open, simple web-scale pubsub (publish/subscribe) protocol capable of notifying one or more Hub Servers (e.g. the reference open source implementation on Google App Engine) of your blog updates so they may be forwarded to any of your feed's Pubsubhubbub enabled Subscribers as quickly as possible.
Any Pubsubhubbub enabled Subscriber can then receive an almost immediate update from any of your Hubs containing the actual update for immediate use. Subscribers know what Hubs to use when subscribing to your RSS 0.92, RDF/RSS 1.0, RSS 2.0, or Atom 1.0 feeds since this plugin will insert one or more links to your configured Hubs into these feeds.
WP Pubsubhubbub has the following features:
As the specification authors state on the main Pubsubhubbub site, the protocol is decentralized and free. No company is at the center controlling it. Anybody can run a hub, or anybody can ping (publish) or subscribe using open hubs.
