There is also a correlation between having an academic background, and having specialized knowledge that is inherently hard to communicate with non-academics. Just because the format was a blog post, doesn't mean that the author was aiming at a general audience. Even if it was possible and desirable, the author might not have had time to flesh out all the concepts that are taken for granted in their field.
I liked the general ideas in the blog. People think about these things informally all the time, but it's nice to see the ideas laid out systematically.
Maybe you can wait for someone to write a blog expanding on these ideas for a more general audience, or write one yourself.
