Dispatch war rocket Ajax to bring back...
Ajax is a made up term, not even original, and JavaScript has always been open.
The term Ajax has done more harm than good, it is JavaScript nothing more nothing less.
JavaScript is a good embedded scripting language, it hits the sweet spot just right.
When you start adding libraries (and I use the term loosely), you add complexity to the script that needn't be there. JavaScript can run quite lean and mean, but not with a load of Don'tJo, Untaculous, or lets use a base of Javascript and amutotype from there.
Call it EMCAScript or JavaScript and be done with it - then there might be interest, but Ajax as a concept is just wrong. See, no one wants the VBScripters, they do everyone's heads in, and that is what AJAX was encouraging.
