To give a clearer example of what I was talking about, look at the linked article from my comment above. It is much longer than the original article from this post, but it (a) starts with a TL;DR, so it gives me a summary that lets me know if I want to read it in the first place, (b) combines detailed original research with analysis and opinion, and, IMO (c) continually adds new information/insights so it builds on itself.

Obviously not apples-to-apples comparison to this article as they have different purposes (original research vs. pure opinion), I just point this out because a bunch of comments seem to be stuck on the idea that I was saying "don't write anything that doesn't fit in a tweet", and that wasn't my point at all.

OK, that's fair -- it sounds to me though that it's less about pithiness, or that this word might be too narrow. To me it sounds like you are talking about accessibility, in the sense that you'd like more care from writers in structuring their writing with consideration for legibility to the reader. In that I am with you
