FWIW, I am sitting at a desk in the Khan Academy offices and am suffering from severe burning due to all the fires people have lit...ok this joke is weird. Not sure what you're using to judge "too long to roll out fully," but we're running pilots in tons of classrooms right now where students are using Khan Academy to move at their own pace. We have 1.75MM interactive problems done per school day. We're using our own data more and more (http://bjk5.com/post/10171483254/a-bingo-split-testing-now-on-app-engine-built-for-khan http://bjk5.com/post/10171483254/a-bingo-split-testing-now-o...) to make the process more adaptive and engaging to individual students, and we've added hundreds of interactive math exercises (along w/ tons of new features: http://bjk5.com/post/8826207372/khan-academy-internship-summer-11 http://bjk5.com/post/8826207372/khan-academy-internship-summ...) in way less than a year. We're nowhere close to where we need to be, and the possibilities for adaptive learning with all of our data make us all salivate for more time. Regardless, I can definitively tell you that every day around here is energized like crazy. We don't lack the fire.
