Please note, there are important differences between the Success Waypoint Desire Engine that I created in 2007, and the "Desire Engine" created by Nir Eyal almost five years later. Nir's work, first published in
TechCrunch, is interesting and useful and seeks to describe how technologies can engage and "addict" users into habit-forming behaviors. Mainly, Nir is using his “Desire Engine” in a way that suggests how professionals playing in the marketing, social application, and game design spaces can "create" desire in their prospective and current users.
