In Search of the Perfect Website

A SmartBusiness story entitled In Search of the Perfect Website talks about ecommerce usability. There are some nice anecdotes about ethnography, redesign success stories, and user comments. It's a bit heavy on the Vividence-style testing and log-tracking (as opposed to traditional or low-budget usability testing), but overall it's good, especially for those looking for (more) hard evidence of ROI for usability investments for ecommerce.
