I see AJAX popping up in discussions ever more frequently these days, an apparent groundswell around the next great thing for solving the perennial issue of delivering a rich client experience over the web. So far I've just been reading and listening. As with all new acronyms, it takes a while to figure out just exacly what the hell its all about. My "Ahah!" moment came after reading an article at AdaptivePath.
I must admit it seems AJAX is more a pattern than a specification, and its by no means clear that AJAX is anything more that a fad. It's not hard to find some interesting and contrary points of view on the web - QuirksBlog for example.
Anyway, after all that reading, I'm itching to at least go for a test drive. Have to have some playtime soon ... and after listening to this webdevradio podcast, I think I may start out with a look at phAtJAX.
