>I don't have a problem with Khan's site existing, but it's disappointing that often answers to requests for learning materials/ideas begin and end with Khan Academy. My personal opinion is that Khan's videos are roughly comparable to an average-quality classroom teacher lecturing about a typical mediocre curriculum.

Its better than average quality classroom teacher in my experience.

And the point is this didn’t exist online at the time. His resources were strictly more. I imagine its still hard to find a single free resource that matches its breadth and quality.
