Since no one has said anything about it -- I really admire the willingness to post a recording of oneself attempting to use someone else's code. A lot of people would shy away from this because viewers might have arbitrary unrelated criticism ("you type so slow!"). This type of thing could be really useful to authors who can notice if a certain concept isn't grasped right away or if documentation didn't immediately solve someone's need.

This is used regularly in UX labs with two-way mirrors and cameras watching how users interact with design -- why should it not be useful to programming as well?
