I thought that since I was involved with the new AJAX stuff in the latest Rails (0.11.1 as of this writing), that I would create a quick demo application showing how to actually use the stuff.
Before you roll your eyes and say: “Ugh! Another todo list example?!”, this one is different! Honestly. Sort of. It's using the new Rails (0.11.1) asynchronous AJAX tools. It's using them a lot. Plus, you can download the source and play around with it.
It's been tested on Safari and Mozilla blends (Firefox/Camino), but not too extensively on Windows/IE. So I'd appreciate a shout out if you find any issues there.
