I have always been fascinated about the quality of information you can get on the Internet. A great example of that is of course Wikipedia
A few days ago I came across another beautiful example The Khan Academy. It’s basically one guy Salman Kahn who is doing this. He started it because his cousin from New Orleans had problems with math at school. Salman, living in Boston at the time, decided to remote tutor her by posting videos with explanations on YouTube. Soon these videos became very popular all around the globe. Salman who holds an MIT engineering degree and and MBA from Stanford decided to give up his day job and fully dedicate himself to making videos. So far he has posted over a 1000 videos on YouTube explaining concepts from calculus, chemistry, biology to getting funding from a VC. Watch the video below for more details.
