I was pondering the origins of the phrase "to call a spade a spade" the other night and thought of asking it here but instead Googled it and got the information I wanted. Even though the information is readily available to any competent web user, should I ask the question here too? If this is meant to be the definitive place to go for answers to English Language questions, shouldn't this be a place where a person could find that information? Or is it just a festival of redundancy?
(I'm not interested in thoughts on the "spade" question -- this is more a "site philosophy" question.)
