My good friend Tristan Louis has some rather insightful things to say about the lessons learned at boo.com, past and present. They were one of the early dot-com flame outs that is being reborn yet again.
Tristan worked there during the early days, and it is instructive to see just how far the world of ecommerce has evolved since that time in terms of multiple currency support, fulfillment services, image handling, avatars and more.
