If content contribution is the problem… Why is updating and extending wikipedia pages not part of normal school or university work. E.g. teams of two students get topic and have to create a value contribution to wikipedia. Not only recite current knowledge but go beyond that and extend the "common denominator" of knowledge called wikipedia. It would teach about research, team work and to some extend about editorial quality and processes. I proposed it once in college. The teacher suggested to bring it to an multimedia course. Maybe the world would be more open today.
