I was lucky enough to be Documentum's first employee in Europe in 1993. While there, I worked closely with Geoffrey Moore and got 'religion' about understanding not just the so-called 'chasm' but the whole marketing model and its implications for strategy, marketing, product, and operational behaviour. I started working with John Newton in the late '80s and we recently discussed marketing models and their relevance to Open Source as well as Geoffrey Moore's new thinking in Darwin and the Demon. This conversation was the root of my thoughts on rules for Open Source marketing - new model, new rules (and some old ones).
