Letters to the Editor is a popular feature in most magazines, and U.S. News is no exception. Positive or negative, reader feedback provides added perspective to any story, and each day we post a sampling of new letters online. For example, our recent cover story, "The Pope and American Catholics," elicited numerous missives from readers; a sampling is posted online. Feel free to E-mail your thoughts about any story on usnews.com or in the magazine to email@example.com. Thanks for writing!
