No, I think GP is right. Compare a typical long-form piece to e.g. a textbook. A well-written textbook has much more information, but still organizes it in such a way so that you can quickly understand what you're getting into. By comparison, I find that long-form journalism typically buries this information so that even if there is a meaningful summary, you have to build it yourself (and obviously you can only do this after having spent the time to read it in the first place).
