>The guy is a rotary engine font of knowledge
I disagree. The word "knowledge" suggests "correct information". I would say that the guy is a rotary engine font of _information_.  Some of the information he adamantly spouts has been proved entirely wrong, yet he has defends it fervently in the face of facts.  Just as little water in your gasoline makes the whole tank dangerous, so information tainted with falsehood devalues all the other information.
Just my 2c, and the reason I'm not on His list.
