User experience designers should look "experience points", a gamification concept, to help them build and design better experience.
Experience points, of the different types of point systems in game design and gamification, are the most important element in a gamification framework.
Experience points are how you watch, rank, and guide your player. This gets to the heart of experience design and user centered thinking.
A good exercise would be to go through your webpages and assign experience points to every activity you want users to engage in. This way you make it explicit how important each is in relation to other actions across your entire web presence. This forces you to look at experience design above the level of page design.
