Ajax for dummies (like me)

Derek Powazek (via the O’Reilly Radar): “[Using Google Maps to explain Ajax is] like using a race car to explain what an engine is. It’s in there, sure, but wow look at it go!”

Great overview of how Ajax works at a very high level. I, like many, have invariably used Google Maps to explain Ajax, but I don’t think I realized that this explanation leaves so much out until I read this.
