If you're a Web developer, you've already started hearing a lot about AJAX. AJAX is a combination of existing programming tools and Web technologies that, according to Nate L. Root of Forrester Research, "leaves the click-and-wait Web paradigm in the dust and enables sleek online apps that feel more like thick client software than Web pages — all without running afoul of the standards police."

What AJAX does, basically, is allow content on Web pages to update immediately when a user performs an action, unlike an HTTP request, during which users must wait for a whole new page to load.
Perhaps the best-known application to use AJAX is Google Maps. The interface allows the user to change views and manipulate the map in real time.
Some observers suggest that AJAX may be overhyped. Forrester's Root calls it "more like a different flavor of Java Applets than a complete Web revolution." Blogger Alex Bosworth thinks its power may lead to dangers for Web developers, as far as introducing UI and server load problems.
