Congrats on your new position! I love Kahn Academy.

Do you think there's any chance that Sal will open up contributions to other teachers? I believe that Kahn Academy could evolve into a MUCH better tool if Sal focused on establishing the curriculum (and which videos and exercises need to be developed), and allowed other people to submit videos from across the internet.

While it's cool that Sal is the sole instructor, he's not the world's best instructor, and I'm sure the overall product could be improved through contributions of others. And you could go from 2100 videos to 10,000 videos a LOT faster if you allowed others to contribute.

Just my 2 cents worth.
