A better way to tell the world when your blog is updated.

== Description ==

This [PubSubHubbub](http://code.google.com/p/pubsubhubbub/ "PubSubHubbub") plugin is a simple way to let people know in real-time when your blog is updated.  PubSubHubbub is quickly gaining adoption and is already being used by Google Reader, Google Alerts, FriendFeed and more. 

This plugin:
 
* Supports multi-user installations
* Supports multiple hubs
* Offers hooks for other plugin developers to add PuSH support to their own custom feeds (NEW!)
* Supports all of the feed formats used by WordPress, not just ATOM and RSS2
* Announces which hubs you are using by adding `<link rel="hub" ...>` declarations to your template header and ATOM feed
* Adds `<atom:link rel="hub" ...>` 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](http://pubsubhubbub.appspot.com "Demo hub on Google App Engine")
* [SuperFeedr](http://superfeedr.com/hubbub "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
2. Activate the plugin through the 'Plugins' menu in WordPress
3. Select custom hubs under your PubSubHubbub Settings (optional)

Note: PHP 5.0 or better is required.

= Does this plugin work with MU? =

Multi-user support was added in version 1.3

= Does this plugin work with PHP 4.x? =

Nope.  Sorry.  For now you must have PHP 5.0 or better.

= Blog posts don't show up right away in Google Reader. Is it broken? =

Google Reader currently supports PuSH for shared items, but not general subscriptions.  Hopefully they will add that functionality soon (I hear they're working on it).  In the meantime, you can check that everything is working correctly by publishing a post and then checking the status at http://pubsubhubbub.appspot.com/topic-details?hub.url=URL-OF-YOUR-FEED
