Academics have said that the value of the Internet is directly related to the amount of information that people can contribute and access. Well, MIT's putting their money where their mouth is, announcing that they will be putting all course material online. Does having the data freely available harm the university's ability to successfully charge tuition? No. People don't pay tuition for the data, they pay for the people - the human interaction with professors and other students. That's where knowledge comes from and it is definitely worth the price of admission.
