Sounds like a great idea, but is this a paid course? If so, I'd personally be worried about it being taught by someone who didn't get in to YC (no offense).
If I misunderstood something, feel free to correct me.
no offense taken ;) it's a free course that I created to help others with their applications and to showcase the prototype of crowdcademy. There will be paid courses eventually, but on much more complicated and lengthy topics such as learning Photoshop or a specific programming language.
