jQuery quickie: Unlimited Scroll using the Twitter API

I'm currently working with Silverlight and implemented unlimited scroll. This is a great technique that could be used on loads of websites. Instead of the regular pagination, where the user has to click to see the next page, unlimited scroll automatically loads the next page when the user is at the bottom.

I wanted to take this technique and port it to another jQuery example. So the quickie for today is Unlimited scroll using jQuery. I've using the Twitter API to make the example, so you'll learn a little bit about JSON too...
