Dr Richard A. Bartle, Senior Lecturer and Visiting Professor of Computer Game Design at the University of Essex, UK is often quoted by, well pretty much anyone involved with gamification... And I'm just about to disagree with him. I just read Will Gamification be Ubiquitous in 5 Years? on Gametuned, and although I believe Dr. Bartle makes a few good points, he's missing some important new developments. Either that, or his and my definition of gamification just don't agree.
