Wow, i watched the first video batch and think it's the best online course so far. Very in-depth, but at the same time incredibly well chosen examples. Initially I was sceptical because the videos seem to be taped lectures rather than the type of screencast I know from mlclass and aiclass, but it's really well done.

There is a notable difference of course between courses like PGM and ML, which go pretty much into details of actual things, while others like AI or crypto will probably naturally stay a bit at the surface, as they are more intended to give an overview. I think they shouldn't be compared therefore. I think the robotics class is a bit behind of it's possibilities compared to PGM or ML, considering that this is definitely not an overview anymore.
