Playing around with Google's AJAX APIs

Google Code Blog: Playing around with Google's AJAX APIs: "For me, documentation isn't always enough to learn about APIs; I need examples that I can play with. That's why I started a fun project recently--a tool for teaching developers how to use Google's JavaScript APIs: the AJAX API Playground. I have been working on this in my 20% time and today I am proud to announce that we are launching the AJAX API Playground as the official way that Google will show JavaScript samples!"
