I found quite a bit in the original article that seemed to point to a misunderstanding of the site for someone who hasn't used it. Karim doesn't even mention one of the most valuable areas: the practice area. It isn't just about watching videos, and maybe I'm alone, but I use the practice first and the videos as supplements. Furthermore, the actual videos seem to often feature explanations in a clear way that does not merely point to following a series of steps (see "why division by zero is undefined")
