I see this regularly on a mailing list where people argue with (who they often describe as rude and cantankerous) the main developer of a certain piece of Internet software. But, what many fail to understand is that the man has 9 RFCs and 2 drafts to his name, and knows the protocol in question pretty much inside out. You. Do. Not. Argue. with him about how things work. His software complies with the protocol RFCs *exactly*. Yet they try... and try... and try again.
