Thought in progress..Been playing with xajax for doing some simple input validations. I still notn get “it” yet, it seems to me that Ajax doesn't really provide me with functionalities that aren crucial for web apps, sure you can do crazy things like drag and drop elements, rollovers,n sorting tables without reloading the page.. but so what? i mean web users expect that n creating request equals to page reloading, unless when ajax later on will become an industryn standard. I have a doubt about it, but will see. n 5 years ago, the hype was Flash, it was said that flash will be the norm for websites, well,n it isn't and it ain't going to be, in fact if ajax gains more popularity, it might replace somen things that are currently exclusive to Flash.
