Douglas Bowman writes about his redesign of the Adaptive Path web site using web standards. If my memory serves, this site was already using standards before, but the new one goes even further in perfecting the technique. He gives very interesting highlights into the resulting design and benefits.
Besides another worthy read about web standards, I noted that they are using Movable Type to drive parts of the site. Another example of the fuzzy frontier between weblog and content management systems.
