"But the curation part of this effort is key. Though there will be a “Wild West part that someone can dig through if they’re in the mood,” he said the designated subjects will be heavily curated"

I am very interested in how they will pull this off. This quote suggests that he'll divide the site into two chunks: curated and uncurated (with overlaps I would assume).

It's a daunting task. I am especially curious how they will select which videos to upload and which to reject (or will they accept anything into the uncurated section?).

I wish Khan the best. Education desperately needs to be disrupted. We are paying way to much for way too little.
