It looks like a free college education for anyone who has the time to read one. I definitely don't have time to read all of this, but there are a few that have caught my interest, and I'm guessing most people can find something on the menu. It's fantastic somebody is doing this for the public good.
Thanks for posting this link! I saw this somewhere else before but forgot all about it. It is pretty cool that MIT has put so much info on the web for people to use.
