" This time last year, a single word began a revolution in Web design. Coined and published on February 18, 2005, by May, the word “AJAX” was on everyone’s lips. It soon became the talk of the entire industry, and has revolutionized Web design as we know it—or, at least, it’s given plenty of bloggers lots to talk about." (Ben Ramsey)

Now it's time for COMET,

"New services like Jot Live and Meebo are built with a style of data transmission that is neither traditional nor Ajax. Their brand of low-latency data transfer to the browser is unique, and it is becoming ever-more common. Lacking a better term, I’ve taken to calling this style of event-driven, server-push data streaming “Comet”. It doesn’t stand for anything, and I’m not sure that it should. There is much confusion about how these techniques work, and so using pre-existing definitions and names is as likely to get as much wrong as it would get right."
