So what is the learnign focus of MMORPGs?

Gibson, Aldrich, Prensky 2007 chapter 4 - OK, so I am beginning to see that MMORPGs are valid environments for learning but that the most valuable kinds of learning might be social acclimation and survival skills and not content learning. I'm having trouble with my own observation that the state of our society is changing significantly in so much that MMORPGs may soon be the preferred way to learn social skills...
