> Do you find them informative? Do they help you somehow? Yes. For any area in which one is not already a specialist, it's good to have some source that can give you a reliable starting information. The internet is full of false, misleading or plainly wrong information, to which I stumble all the time. It's even frequently multiplied across many sites where the "content" is produced by rewriting (or mostly stealing) the content from some other site, and the quality of the information multiplied is irrelevant. So you can even get the impression that the answer is right, because you see the same on many places! So it's worth having a source even for the introduction-level information for which you know that is reliable and nicely summarized. I've already recognized that Julia's material is that. I can surely recommend Julia's work to anybody who needs a reliable start in some of the topics she covered.
