Has the website code been open sourced?

I'm not staff, but I believe that only some parts of the website are open source, the most notable components being Presus (extercise display and grading) and the "Live Editor" from the CS extercises.

You can see a list of open source Khan Academy projects here: https://khan.github.io/.

To my knowledge it is mostly not open source, and I support open sourcing the code.

As a hacker, I would definitely approve more hacking opportunities >:)
In all seriousness though, that sounds nice! But it could open up the ability for malicious hacking.

github pull requests would really be nice. there are much benefits of beign open source

Are there any updates on this?
