Someone whose maths teaching videos aren't very popular complains that hers videos are better than the videos which are popular. Khan academy isn't popular because he has money from Bill Gates, his videos were hugely popular on youtube long before that, for the simple reason that they satisfied user demand. She needs to ask herself why there's more demand for people who want to learn about "mean, mode and median" than there is demand for learning about "levels of measurement and sampling methods". I'm guessing most kids and adults will never have to design randomized trials and data collection, but they will come across averages in every day life. From her description she mentions how she spends a lot of time thinking about theory of teaching and rewriting and editing to correct mistake and edit out hesitations, what was noticeably missing was any discussion of applying user analytics, A/B testing, etc. to better understand how her users were interacting with her videos, when they were losing attention span, etc. One of the reason that Khan Academy is successful is they take a very metrics driven approach to iteration, something that should be very familiar to any startup founder. Sure Khan's videos are flawed but people want to watch them. It doesn't matter how much better pedagogically Dr Nic's videos are if people don't want to watch them.
