I really like the idea of this kind of thing, but I thought it was going to be nicely animated presentations. I was disappointed to see it's that Hank guy talking. He speaks in an annoying version of a newscaster voice, and it's distracting that they keep showing him instead of focusing only on the content. He also speaks too fast and jumps over concepts. It's disappointing that the most popular pop science stuff on YouTube involves this guy. I'd rather something more like Khan Academy, with better animations. He speaks in a more normal voice, and goes slow to really cover a concept.
