I am excited about the PubSubHubbub project, and was amazed by its simplicity and scalable design.
I finally downloaded the MovableType PubSubHubbub plugin and installed it 5 minutes ago. If it works as it is expected to work, and after Google Buzz and other crawler update my RSS XML the next time, the magic will happen. You will start to see my blog post in real time (well, almost real time by few seconds delay) in your Google Buzz. With more and more services supporting PubSubHubbub, more and more people will see this real time functionality.
What is it
Simply put, PubSubHubbub, despite of the weird name, is a very easy and simple protocol.
Every time I hit the “Save” button in my MovableType editing page, it will ping a server called http://pubsubhubbub.appsport.com (it can be any other similar services, I just used it as an example), and that server will ping all the subscribers, like Google Buzz, to tell them something has happened. Then they will get back to my blog to get the latest entry. That replace the current pull method – readers needs to check at an interval – waste of time, and can be huge delay.
Real Time Web
The web is continuously changing. I am excited to enter the real time web today.
