My son and I attended the great debate at Melbourne Town Hall on March 4 where the proposition under debate was “that Australia should embrace nuclear power”. After the panellists finished speaking, the moderator invited questions from the floor. That experience made me especially interested in this posting on Tyler Cowen’s Marginal Revolution blog – why do people ask questions at public events? According to Tyler, “the ‘really want to know’ motive is not absent altogether but I really doubt if it is primary”. As a consultant myself, I think there should be a separate “marketing” category, too.
