I never said that you "can't explain things" with video. I said that your videos work very well for review. The medium has changed, but you're doing the same thing that has always been done. If the goal is to get past a test or quiz, then I'm sure students love it. But will they understand it in a month? Two months? A year? They won't come back to leave those comments on youtube.
I simply ask you to watch the video, and respond to it. I think it makes valid points, and it agrees with the research I've read on how students learn (Available for free here: http://www.nap.edu/catalog.php?record_id=10126).
If you truly want to build, and learn (which I certainly want to), don't flippantly dismiss critiques. Just because all forms of effective teaching don't go viral on YouTube doesn't mean that they're invalid.
