Geoffrey Moore's prescription for marketing types and company officers in high tech industry suffering from eCommerce/Internet complaint is TALC, the Technology Adoption Life Cycle (ha, was that supposed to be funny?). Originally written in the mid 90's so I've made allowances for the lack of empirical evidence for Geoffery's assertions which seem to based more on gut feel or instinct. TALC and the Inside the Tornado has too much intuition, read Hal and Varian's 'Information Rules' if you want to find out what is really going on. Unorganised, poorly edited and of little current relevance.
Over uses 'to be sure'.
