Wouldn't some of what this article describes happen simply because of specialization? As the knowledge in a field broadens, no one person, less so a person outside the field, can read and keep up with the publications. Therefore a single field can have 40 journals. And, some topics really are complex enough that they cannot be explained in an "easy-to-read" format because they require an enormous amount of context.
