Jared Spool has this nice little presentation about Design Treasures from Amazon (there are four of them, or at least four that he’s willing to talk about).
The presentation is worth a listen, particularly for anyone who manages a large website and wonders how to keep making it better. The quickest answer I can give it: don’t redesign (evolve), and takes risks.
There’s also this gem of a slide which reveals how Amazon can always offer products for less.
