A better way to tell the world when your blog is updated.
== Description ==
This [PubSubHubbub](https://github.com/pubsubhubbub/ "PubSubHubbub") plugin is a simple way to let people know in real-time when your blog is updated. PubSubHubbub is widely adopted and is used by Google Reader, Google Alerts and many other services.
This plugin:
* Sends realtime notifications when you update your blog
* Supports multi-user installations (Wordpress MU)
* Supports multiple hubs
* Supports all of the feed formats used by WordPress, not just ATOM and RSS2
* Supports latest spec ([Version 0.4](https://pubsubhubbub.github.io/PubSubHubbub/pubsubhubbub-core-0.4.html))
* Announces which hubs you are using by adding `` declarations to your template header and ATOM feed
* Adds `` to your RSS feeds along with the necessary XMLNS declaration for RSS 0.92/1.0
By default this plugin will ping the following hubs:
* [Demo hub on Google App Engine](https://pubsubhubbub.appspot.com "Demo hub on Google App Engine")
* [SuperFeedr](https://pubsubhubbub.superfeedr.com "SuperFeedr")
Please contact me if you operate a hub that you would like to be included as a default option.
== Installation ==
1. Upload the `pubsubhubbub` directory to your `/wp-content/plugins/` directory
