This article gives you a good understanding of the fundamental principles of Ajax and a nuts-and-bolts knowledge of the client and server side components that participate in an Ajax interaction. These are the building blocks of a Java-based Ajax Web application. In addition, you will be shown some of the high-level design issues that come with the Ajax approach.

Member since:Google Maps also does something this article didn't mention. It uses XSLT.
A client-side XML dataset that is transformed into HTML nodes is a very powerful concept. (Potential memory leaks aside).
For the laggards Google even implemented an XSLT Processor in Javascript! (Safari and Opera). And made it available:
http://sourceforge.net/projects/goog-ajaxslt/
Event code in Javascript, datasets in XML and displayed using XSLT. Thats the power of AJAX.

XMLHttpRequest may have made it simpler. Google Maps may have made it popular. But Asynchronous Javascript calls existed and were used a long time before both of them. As for the XML part... not only is most of the times unneeded, but also many applications prefer to skip that bit for a (small) speed gain. But anyway, nice article as introduction to AJAX.
@jessta: "Wonderfully AJAX usage will be kept to a minimum."
Or not. Of course you shouldn't impose too much restrictions on your visitors if you have a public website and want it to be popular.
But if you can, you should use what is best for the experience. Take Google Maps, for example. Sure, you can have a reduced version for those who can use the full one, but the whole point of Google Maps is the interface (and arguably the published API they provide).
