Recently I started using Khan Academy a lot more. At first I too felt like a lot of the videos needed more polish, as well as some other aspects of the site. But eventually I accepted that it really didn't matter whether I was watching one of the newer HD videos or the older pixelated ones. It wouldn't help me learn. I think the informal style is a plus. Making the videos more professional would risk them being the same thing as a textbook. In my math class, we occasionally do "flip teaching" using brightstorm [1]. Its basically a more formal version of Khan Academy, and I think the videos are super boring to watch compared to something like Sal's video on the squeeze theorem [2].
