I think we should encourage posts which are well-delimited and research based; "here's a question I had, and how I answered it in a finite amount of time" rather than "here's something I've been thinking about for a long time, and here's where I've gotten with it". Also, this is an engaging topic and well-written. I feel the "final thoughts" section could be tightened up/shortened, as to me it's not the heart of the piece.
