I've watched two of her videos and think she is a talented explainer. But I think she needs to have more people read her scripts before getting in front of the camera, because both of them contained glaring errors. Since she bristles and gets rather defensive when her errors are pointed out, I am not optimistic that these videos are going to get much better. In short, I don't see how being “a layperson familiar with these people” informs you who us correct and who isn’t in any particular instance.
