Like newspapers, universities are trying to figure out how the web changes their business model. On the Johns Hopkins School of Public Health site:
The Johns Hopkins Bloomberg School of Public Health's OPENCOURSEWARE (OCW) project provides access to content of the School's most popular courses. As challenges to the world's health escalate daily, the School feels a moral imperative to provide equal and open access to information and knowledge about the obstacles to the public's health and their potential solutions.http://ocw.jhsph.edu/
Is that what's motivating them: a 'moral imperative' to provide learning opportunities to those who can't afford a 100K education?
