The Pope's on Twitter! When the Vatican announced he would start tweeting under @pontifex last week, more than 625,000 people registered to follow his account in English. Tens of thousands more are following his Arabic, French, German, Italian, Polish, Portuguese and Spanish accounts. His first tweet? "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." It was retweeted more than 7,000 times in the first twelve minutes. Will the Catholic Church expand its influence among the Youth? It certainly hopes so.
