Dear Khan Academy,
Khan Academy is such an inspiration, such a great example of not waiting for license or funds to start innovating – it all started with one individual wanting to make a difference (and to teach his nephews :-).
Thank you for the time you put in in creating these, and not only teaching kids lessons, but also teaching a lesson in innovation and looking at education from a new, tech-friendly perspective.
Congratulations and thanks for the new, free iPad app.
Khan Academy rocks!
