PubSubHubbub (Use as PuSH in short) is publish/subscribe protocol addon to the current Atom/RSS technology. It enables your RSS subscribers to instantly receive your feed as soon as you publish your content.
On March 3rd, 2010 wordpress.com turned on PuSH support for the more than 10.5 million blogs hosted on WordPress.com. There’s nothing to configure for wordpress.com hosted blogs, as it works behind the scenes. However, for self hosted blogs which are running on the wordpress platform it needs to be done with the help of PubSubHubbub WordPress plugin.
What Does PubSubHubbub work ?
when you publish a content, it doesn’t get push to the feed aggregation automatically. Instead, the feed aggregation poll your site (RSS feed) at regular interval and check if you have new content. If yes, it will then broadcast to your subscribers. With this push technology, there is often a delay in syndication and it could be several hours after your content went live before your RSS subscriber can read it on their RSS reader software.
PubSubHubbub aims to get rid of this time-delaying barrier and make everything real time. This means that as soon as you publish the content, your end subscriber will also receive it instantly.

How to Install PubSubHubbub ?
This plugin does not implement a hub, but it allows you to select which hubs you want to ping. The default is Demo hub on Google App Engine and SuperFeedr. After Installing this plugin you need to select custom hubs under your PubSubHubbub Settings which is of course optional.
