Infinite Scroll + HTML5 History API

Note: This is broken right now, as I need to update it to use the new Twitter APIs. Yay security!

This example shows the power of the History API when combined with infinite scroll. Fluid user experience and hard linking all in one. Scroll down, click a link & press the back button, refresh the page — it all just works (well, mostly — still needs some polish).
