While sites like Coursera and Udacity have been drawing the most attention on the free education front these days, Saylor has largely flown under the radar. Created in 2008, the site offers nearly 250 free courses online, with topics centered on the 10 highest enrollment majors in the U.S. In addition to taking classes, learners can participate in discussion forums (organized by topic), track courses and print transcripts, and may soon even be able to access free textbooks.
