Ok so this isn't exactly a documentary but more of a interesting conference talk at TED from Salman Khan, the creator of www.khanacademy.org. He explains how he came to create this fantastic site and the great potential it has to benefit todays society. I came across this video today and I felt I should share it as it really is a great site, in all honesty I have known about this site for quite some time now and in fact it has actually helped get me through some pretty tough college semesters.Well worth a look!
