IT's an interesting Idea.. one fault is that people who don't pay for it don't end up getting the information.. but *shrugs* for people who can learn through them.. I say why not? It cuts down on the amount of people in the lecture hall and gives students more ability to ask questions in class. If it's a resource you can use great.. I don't think uni's have the responsibilty to worry about weither or not the students are lazy and come to class. It's not their problem.. so all in all I think it's a decent idea. Honestly, I learn better when attending lectures and I paid to get there, so why bother skipping? honestly...
