Boo Hoo: A Dot Com Story about one of the first and biggest .com crashes. Its an entertaining read, and changed my sympathies for the founders. I'd love to say their downfall had a KM basis, but from what's reported it seems largely financial. Mind you, there's no way that their rate of expansion could have supported inter-office learning. Some transfer happened by good old fashioned 'people flying around'. So I'm sure poor KM at least contributed to their scary burn-rate.
