IN the first year that MIT had OPenCourseWare online, I followed a online and meatspace group of English speaking Indians who went through every economics course available. Learned quite a bit through following their conversations.
Was an interesting experience.
For economics... I suggest mises.org for freepers.

Hey thanks for the links. I was wanting to check some of them out.
Must have been fascinating.
