To be perfectly honest, your last sentence is also my feeling. I should at the least have talked more about the key equation. But the article was already long, I was unsure as to how it would be received, and I spent too little time revising it (this is a persistent problem for me). If I were to write it again now, it would have been closer in style to the thread between you and me there.

If you intend to write another post, then I am happy to wait until then to introduce the ideas I have in mind, and I will try hard to do so in a manner that won't alienate everyone.
