Some of you accuse Khan of being an accessory to a nation wide assassination of math. Others seem to hint that he has no integrity. And the rest of the discussion has more relevance to teachers and their plights then actually benefiting the student IMO.
So, with all due respect, why don't you take advantage of the information technologies which became widespread in the last 10 years, and join the effort of making high quality mathematical education available to anyone ? Internet makes this possible.
Do what N Wildberger , C. Tisdell and a guy nicknamed "Mathview" do on youtube, what H. Gross does on his homepage or what A. Schremmer does with his freely available books and make available to masses high quality math education.
Take advantage of video media, publish over internet, and I promise you, if you deliver high quality people who want to learn (i.e not monkey see monkey do types) will choose your channel over Khan's. I'm waiting your contributions ladies and gentleman's, and in addition to helping humans, you will also meet your goals of getting good public exposure of what you consider to be good math education. Kill Khan's misguided ways by by doing better.
