At least, that will be the case if RedesignMe! takes off. The site is a collaborative database of poorly designed products (uploaded by regular folks), and helpful suggestions about how they might be made better.
While there's no focus on self-service per se, I can certainly think of a number of kiosk apps that I've encountered in the past that could have used a bit (or a lot) of design work.
