John works mostly as the maintainer for the Khan-exercises open source project, basically the Exercise Dashboard piece of Khan Academy. Remember, it's open source[1], so don't hesitate to join in and help revolutionize education. There's some very cool and interesting things we're working on that get used by millions of kids (and adults!) everyday. You know some js, python, HTML/CSS? Interested in documentation, searching for bugs, or doing usability testing? You're cordially invited. [1]: https://github.com/Khan/khan-exercises https://github.com/Khan/khan-exercises
