How Did That Chain Letter Get To My Inbox?
Everyone who has an e-mail account has probably received a forwarded chain letter promising good luck if the message is forwarded on to others--or terrible misfortune if it isn't. The sheer volume of forwarded messages such as chain letters, online petitions, jokes and other materials leads to a simple question--how do these messages reach so many people so quickly?
