I heard about AJAX about 3-4 month ago and now currently try to learn about it. Supprised me that AJAX is powerfull. I called this should be advanced solutions for web development. Using JavaScript and DHTML we can build rich internet applications (RIA). Uhh that why most people always try to compared between flash and AJAX if we talk about building RIAs.

And today I found this a nice articles about AJAX, why people should love it and the alternatives.
