I’m really excited about this. Last year I signed up for one of the Stanford University online CS classes, and it was pretty cool. I got what I wanted out of it and was able to use it effectively at my job. It was an interesting experience, moving the availability of education in the direction of accessibility, but not to such an extent that it would replace existing structures.
Edx, however, will be potentially disruptive to the academic industry and I’m eager to try it out this fall. I don’t know if anyone will be able to acquire a formal degree (seems doubtful) but we’ll see.
