All WordPress.com hosted blogs just beaten others in becoming a really real-time online content property. Thanks to Pubsubhubbub or PuSh as what some people have shortened it to, each and every posts you published on your WordPress.com blog will now be pushed automatically, in real time to the web. This means, real-time feed push to RSS aggregators such as Google Reader, Bloglines, Friendfeed, Netvibes and others.
Basically, what PuSH does is to let your feed aggregators to register automatically to receive updates from your blogs each time you publish new posts. These updates are sent out within a second or two after you publish a content. Previously, the process is a bit tedious since your blog is periodically being asked by these aggregators if there are any updates before notifying those who are using the service.
The service was automatically activated for all WordPress.com blogs, so there’s nothing that you need to do to get it going. If you’re blog is not hosted on WordPress.com, you can still have this feature by installing a new plugin which you can download from here.
And if you want some more information about PubSubHubBub, you can may want to check out project site or the Google groups. If you don’t have any idea what PubSubHubbub is – TheNextWeb describes it as:
An open protocol for distributed Publish/subscribe communication on the internet. The main purpose is to provide near-instant notifications of change updates, which would improve on the typical situation where a client periodically polls the feed server at some arbitrary interval.
