Popular EdTech sites, November 2013

Inspired by an old habit in my old startup, I decided to start a monthly update on the popularity of EdTech sites. Well, those updates should last as long as I am still in the EdTech industry.

A very incomplete and working in progress list are here. The Alexa rank is not necessarily accurate but nevertheless a good approximation of the popularity.

https://www.khanacademy.org/  4,476
https://www.udacity.com/  7,042

Notable mentions for Asian companies, because for them, Alexa is useless.
