I cannot limit my nomination to a single post, because it was the several Robert Rapier posts on ethanol and Khosla that made the biggest impression on me. If I had to list one single post I'd be in a tough spot, because there were about ten or a dozen tied for first place, and from all of the editors, contributors and senior contributors on on the list. Probably of all the contributors, Khebab most influenced my thinking, but that is just edging by a hair others from first place. Where would we be without Stuart's posts?

Darn it all, just picking one posting does not work for me.

Leanan made large numbers of the best comments; I rate her input as A++.
