I think that the college experience includes a lot of interaction and feedback that you can't get by reading lecture notes or watching videos online. You do problem sets and write research papers and then get back comments on your individual performance. You take tests and can see what you got right and what you got wrong. You do lab experiments using equipment that's not available to you at home. If you study a foreign language, you get critiqued on your pronunciation. I think online courseware is a fantastic resource, and I'm very happy it's out there, but using it is nowhere near the same as attending a university in real life.
