Two days ago Scott Aaronson have commented on this topic. At this moment, his answer has as many upvotes as the Ron Mainmon's one (former most upvoted one).

Scott enjoyed the sequence and thinks that it is "exactly what you should and must do if your goal is to explain QM to an audience of non-physicists". However, he gives two criticisms of Yudkowsky, both connected to the Eliezer's claim that MWI vs CI debate is completely one-sided.

And, as usual for Scott, he nailed it, too

How accurate is the quantum physics sequence?

Prompted by Mitchell Porter, I asked on Physics StackExchange about the accuracy of the physics in the Quantum Physics sequence:

What errors would one learn from Eliezer Yudkowsky's introduction to quantum physics?

Eliezer Yudkowsky wrote an introduction to quantum physics from a strictly realist standpoint. However, he has no qualifications in the subject and it is not his specialty. Does it paint an accurate picture overall? What mistaken ideas about QM might someone who read only this introduction come away with?

I've had some interesting answers so far, including one from a friend that seems to point up a definite error, though AFAICT not a very consequential one: in Configurations and Amplitude, a multiplication factor of i is used for the mirrors where -1 is correct.
