I thought this was a great article because it was very thorough and to the point. For me, the business lessons from the internet startup world seem to be transmutable to brick and mortart business and back again. Sam Walton's autobiography (Sam Walton: Made in America : My Story) has a list of advice at the end of the book that describes what he thought made Wal-Mart successful. I think this list is something that would be very applicable to the internet startup world.
