Dear wildbill,
Some of the best books never make it to the best sellers list. On the other hand, they’re intensely popular with people who have specialized interests, and these books have had multiple editions printed out over many decades. Two books that come to mind are: The Worldly Philosophers (economics) and The Road to Serfdom (economics; Hayek).
So, as to who is SunkenCiv?
Good question. He/she puts out the astronomy photo of the day and most of the godsgravesglyphs articles on Free Republic.
;-)
Sunken and I have a very friendly and joking relationship going back several years.
I love to tweak him about his posts and he tweaks me back.
As to who he is, his name is Etaoin Shrdlu. He is the last survivor of an alien civilization that crashed into the sea eons ago. This is all documented on the History channel series on Aliens visiting Earth as Gods.
And wildbill traces his ancestry back to ice-age mammoth hunters.
