Many people think of YouTube as a big time-waster with nothing but videos of animals dancing and guys getting whacked in their privates.

But as time goes on, I become more and more conscious YouTube as a great resource in many respects.

Khan creates his videos on a tablet computer with pen input. Here’s an example of a video explaining the basics of banking:
