I don't get the point. There really isn't anything particularly inherently special about blog posts as a medium versus say, chapters in a textbook, other than the obvious things. You can, of course, learn about complex subject matter through a blog post. If you find someone with a similar mental model of things to your own, I think you can in fact learn from blog posts easier, as they can get from zero to understanding with less detours. On a similar note, I personally believe there are many concepts that have been explained much better by random YouTubers than academic textbooks. Textbooks are more comprehensive almost always, but having an intuitive understanding of something is obviously more important in many cases than simply remembering a long list of bullet points about it. You can always use reference material later. In real life, memorizing facts on their own is rarely useful. The best answer here is that you should use both, or imo, "all three," of blog posts, video content, and academic textbooks/articles/courses. Taking a variety of approaches helps me get to a mental "click" quicker, personally.
