A great idea.
And almost on cue, old-school designers on twitter (who could probably learn a lot from doing these courses) are sniffy about how you can't just learn design by doing courses like this... Imbeciles.
I think this is a really interesting idea. Like LivingSocial starting HungryAcademy http://hungryacademy.com to find/create more programmers, startups seem to have a need to fill when it comes to design.
It will also help those independent developers who don’t have the luxury of working with a designer at least start from a better understanding of design… if the program is structured well.
