I actually have to questions to you. One is regarding your book and the other regarding your AJAX experience.
1. What is it, that makes your book the best buy or exceptional (in some topics maybe) compared to the majority of AJAX Books which are already available?
2. What do you think about the amount of different AJAX/JS Frameworks. Have you got some experience using one of the frameworks together with some JAVA MVC frameworks. I'm currently using the Dojo Toolkit, fed by Spring MVC.
