One thing why I love this model is that it allow for mistakes to be made. Try doing that in a corporate environment. :X With each mistake he made, he get interactions from its students/viewers. Ultimately this makes students/viewers more engaged with the material and more connected with him.
To think that overall, he's collected about $150,000 in donations and makes $2,000 a month from ads on his Web site. I love it! Got a passion, what are you waiting for? The barrier for entry is almost non existent!
