I noticed yesterday that the premiere poker site with all the biggest stars is relying heavily on jQuery: http://www.fulltiltpoker.com
They use jQuery 1.1.2 and a bunch of plugins as well, including the Thickbox 3, Metadata, Validate, Slider and Media plugins. See http://www.fulltiltpoker.com/js/common.en.js for more information. -- Suni
