Information Letter 14. This memo by John Walker was one of my touchstones more than a decade ago. Written in 1991, it talks about the quaint Eighties. It's amazing to me how much changes with the Internet and how in many ways nothing changed.
I rate this a must read for everyone. Actually, his whole book is very interesting documentation about the creation of Autodesk and like all true stories, it's not pretty to see how things really worked in a sausage factory
