Dan G. Switzer, the main main behind the awesome qForms Javascript Validation Library has been frequenting the jQuery discussion list. Looks like he's also taking advantage of the very hot jQuery Ajax/Javascript Library for his projects.
Its great to see the jQuery library continue to make inroads in the ColdFusion community. And with Rob Gonda releasing AjaxCFC for jQuery, there's no reason why you shouldn't take a look at this great library.
