I enjoyed this but on the surface reading didn't like his "it makes me think an octave higher" line, and on reading the context from Sivers (an excellent article that, btw) I even more didn't like it. The analogy just didn't seem appropriate. However, after some thought I felt the paragraph after with the bulletpoints does actually line up quite nicely (albeit rather obliquely) with what Sivers was talking about and I think I get it now, the finer points just weren't immediately obvious. This a minor niggle but I think that he could have explained that part better, and without requiring a whole other article for context (no matter how good that article is!).
