Thanks for your feedback, appreciated! And glad the Garbage Collectors class is interesting. Yes, I'll consider shortening the intro in the future classes. Initially each lecture was a self-contained, and potentially with no related context to previous lectures, however when combined in a class, yes, it makes sense to make the intro shorter. In the Interpreters class I shortened it to ~5 secs only.
