Pope Benedict XVI pushes a button on a tablet at the Vatican last December. In perhaps the most drawn out Twitter launch ever, Pope Benedict XVI pushed the button on a tablet brought to him at the end of his general audience Wednesday. It read: "Dear friends, I am pleased to get in touch with you through Twitter. Thank you for your generous response. I bless all of you from my heart." (AP Photo/Gregorio Borgia)
