Ahh, I took the original one on Coursera, and had no idea about these edx courses (which I must now find the time to do.)
The course made a huge impression on me. In particular, the jaw-dropping moment of realising, "I just wrote a set of mutually-recursive functions, and they worked first time, and it was easy"
At work at the moment I'm mostly maintaining and extending a system that I've been working on for the last few years, and when I look at my old code, I can see instantly whether it was written before or after taking that course.
