I think it looks great, with the greatest benefit being everything about it finally in one place. I might only add links to Wikipedia, Wolfram, and/or Wherever as a "further reading" section. Maybe we just need Snyder's book in Sphinx format ;)

Sphinx sure does make for some pretty documentation when you put in the effort. I will work through automated PDF generation of the website in addition to the currently existing HTML. We have this for PDAL and MapServer sites as well, and we have found it very valuable for snapshotting documentation in conjunction with releases.
