You say: "Ironically, Microsoft unintentionally helped create Ajax. The x in Ajax is from the XMLHttpRequest object, which lets the browser communicate with the server in the background while displaying a page. (Originally the only way to communicate with the server was to ask for a new page.) XMLHttpRequest was created by Microsoft in the late 90s because they needed it for Outlook. What they didn't realize was that it would be useful to a lot of other people tooÂin fact, to anyone who wanted to make web apps work like desktop ones."
I think that's slightly off -- I think the folks who designed XMLHttpRequest fully understood its general utility. I think they're thrilled that lots of really interesting apps are being built on top of it. I think the problem was that the people writing apps at Microsoft didn't realize you could now use this to write compelling web-based apps.
