A few days ago I blogged about the update to Spry. I've updated my demo. You can see two AJAX-ified Blog demos:
Demo 1 is the same as the last one. View source to see how the mark up has changed.
Demo 2 is a slightly more powerful demo. It lets you sort the results (although date sorting is broken now).
All in all - I continue to be extremely impressed with Spry.
