Agreed. Mozilla may have helped change the browser landscape, but the Khan Academy could change the face of education in this country. Both worthy places to pour one's energy but I'd give the edge in excitement to KA.

It's not just one country. I sincerely can't express my gratitude enough for Khan Academy guys, their very rich educational materials have and are helping me tremendously in my education and my career. I'm from a developing country.
