How Khan Academy Is Going Global

Khan Academy is on the leading edge of breaking the traditional models of education.  You've probably heard about it.  TechCrunch had an interesting article on how they are incorporating international transcribing of subtitles.

This is interesting from several perspectives:

1. Universities are going to be to expected to make subtitles available for required course videos used in online education.  While tools exist for automatic subtitling and Google's YouTube can do this, it will be interesting to see how this affects distance education.
2. The spread of language translations might be an interesting indicator for technology diffusion.  Why is Estonian the language that videos are most frequently translated into?  
3. Helping with this translation process could be a great way for international students to have some unique resume material while working to make a difference in the lives of younger students from developing countries.
