WordPress.org

This 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
• SuperFeedr

Please contact me if you operate a hub that you would like to be included as a default option.
