Online newspaper polls are mostly a waste of time, as they tend to self-select for trolls and don't come close to representing what ordinary people really think. So congratulations to the Contra Costa Times, for demonstrating the vacuity of such polls once and for all. Today's question: "Who was the greatest superhero of all time?" and the candidates include Superman, Batman, Underdog, Hellboy, Silver Surfer, Storm, Wonder Woman, and Ghost Rider. Note to Times editors: superheroes aren't real.
