XUL and XAML at 4 PM "For those of you Mozilla folks who are interested in XUL, I suggest you pay close attention to what Microsoft is going to unveil next week at the PDC conference. The massive new Longhorn API will be revealed, including XAML, Microsoft's own markup language which is similar to XUL, but way more powerful. It's flattering to know that Microsoft is modelling the future of Windows UI development after a technology we all worked so hard to bring to life for Mozilla. We were truly ahead of our time.
Click here (http://msdn.microsoft.com/longhorn/) on Monday, October 27th and keep a napkin handy to wipe the drool off your face. And please, spare me complaints about how this is not a cross platform technology. Who cares, it's going to be so mind-blowing that it will make huge waves in the industry regardless."
