 How to build an app/service that makes all users feel equally smart?
10ren: A bit tangential, but there's the idea of aiming at average - as in the "Family Feud" TV game-show, where you have to predict the most popular responses to a survey.Another approach is to reward the user at every possible moment: the casual game "Peggle" has been immensely popular (because of this, I think). There's still the same information feedback, but presented in an upbeat way. I'm charmed by it despite myself.
