So I think one need to avoid clichés and presuppositions about "non geeks". Indeed. And the concept of dividing the world into geeks and non-geeks is flawed to begin with, because non-geek covers so many different kinds of people, like kids, chemistry professors, Belgians, housewives, the mentally retarded, taxi drivers, muslims, the poor, the rich, and on and on. The "average user" doesn't exist (and isn't called Joe).
