I prefer when authors lead with the conclusion and then spend the rest of the essay supporting it.
I hate long essays that bury the lede, and force you to read through paragraphs of bloviating and pontificating until they finally get to the point. Save that for the fiction novels.
Whenever I come across an essay like that, I either skip reading it, or read it backwards starting at the end conclusion and then working backwards to see how it was justified. Marc is just saving me some work here.
