I remember Payne saying he listened to lectures and learn-y stuff while he worked. So when I was going through the March 2011 Reader's Digest, I thought of y'all when I saw the article entitled "College For Free". The article itself can be found here: http://www.rd.com/money/how-to-go-to-college-for-free/
But there's also a list of free classes that I didn't see in the online version of the article. They (and a paraphrased summation) are as follows:
iTunes U: "learn anything, anytime, anywhere."
Academic Earth: (academicearth.org) Browse lectures and post questions or comments.
YouTube EDU: (youtube.com/education) Apparently there's tons of shit there.
The Einztein Knowledge Network: (einztein.com) Access to completed courses including downloadable syllabuses, etc.
Khan Academy: (khanacademy.org) One guy lecturing on lots of stuff. Mostly numbers and science.
Open Culture: (openculture.com) Guide to free audiobooks, language lessons, etc.
If y'all have any other links to throw in or comments on these 'uns, feel free to toss it in. The more learning, the merrier.
Cool! Liked that article on what people want from grads.

Open Culture is the newest one I've found. Not just for courses either. I've been introduced to some awesome Orson Welles film noir through that site.
Wikibooks has some good stuff.
Some of it is crap too (or at least, The Muggles Guide to Harry Potter probably isn't what you're after) but the good stuff is worth it.
the teaching company has great lecture series on audiobooks. they aren't cheap if'n you have scruples, but if you misplaced those, then there's tons of the series on the bittorrent networks.
i listen to those on my commute.
I've heard a lot of good things about Khan Academy. My son's teacher recommends it highly.
