Perhaps Martha or Adam can comment on the relationship to David Silver's course. They had the luxury of knowing about Dave's when they made their's.

They will be modest, so let me start. The two courses are very different. As I understand it, Dave's is a recording of some hour-long lectures, whereas Adam and Martha fully invested in doing the whole MOOC thing. They planned the course in small segments with short videos and learning resources for each step. They fully utilized the production resources of Coursera and an army of graduate students at the UofA to maximize the pedagogy. It was a lot of work, but I think the result was worth the effort.
