After finishing a round of history, I started in on various other subjects. In most areas besides history, the links to specific nations and peoples of the world are far less advanced.
The connections of my personal studies group were fairly uselessly abstract, but I took the opportunity to add a few more pages for individuals in the biography list. The added connections of various parts of anthropology to various nations also weren't very useful. The highly abstract principal areas of culture also weren't much help.
Since I was skimming the surface and not getting much in useful connections, I decided to go to a deeper level. Although I mention that I want to get into economics, I didn't get much beyond reviewing what I have already done. Government did better. I wound up connecting some of the larger nations to different areas of government, which gives some advance in content. Religion still isn't as well developed as I would want, but I got several nations to have a little more about religion in general.
