The "forward thinking" comment was facetious.
I don't know why you have so much trouble with the term AJAX. It is a perfectly good, pronouncable acronym for a combination of technologies: Asynchronous Javascript and XML. What is the problem with that? It doesn't "dumb down" anything, it simply provides a simple and descriptive term for a cumbersome phrase. If that makes it more accessible to people, so much the better.
As for explaining the concepts of AJAX. Why should that be necessary when others have done it much better than I could? I learned about AJAX the same way I told the OP to: I googled the term. If I point them in the right direction they'll find the same sources I did, and learn the same things, perhaps more. If the OP is too lazy to do as suggested, then TT is probably not the place for them anyway. We are here to help each other, not do other people's work for them.
As tsuji pointed out, I could have provided some actual links, and I will next time. But there's no point in trying to describe something that has already been described elsewhere in much greater detail, that's why people here link to other threads and other sites all the time. Why rewrite a whole description for one posting (and do it again the next time)?
