As a semi-pro writer, and on some of my longer comments, I've typically written something out, taken the last idea that came out as a result of that writing process, and pasted it to the top/front of the piece because that's the idea with the most time, effort and value I can add. Leading with that rewards the reader with the value up front, and then they read on for more, which includes my initial reaction and analogies that produced it. Remember that most people who write are still sounding out ideas when they write, so the final paragraph or final chapter of a monograph is where to start with most things. Then I read them in reverse order. If it's professionally edited, you can read the first few parts because the editor will have uncovered any buried ledes and popped them up into the front matter. In journalistic writing, the opinion ("context") they were trying to freight the piece with is at the end.
