mikesd81 writes "Over at the Baltimore Sun there is an article about the post office removing those blue corner mail boxes because of e-mail. From the article: 'As more people send e-mails and pay bills online, the decline in first-class mail is forcing the U.S. Postal Service to remove tens of thousands of underused mailboxes from city streets.' The article goes on to say that the boxes were an American icon: 'You recognize them in Chicago, you recognize them in D.C., you recognize them in Florida, you recognize them in Montana,' Pope said. 'It's a piece of American iconography that has a wonderful history behind it.'" What the article forgets to mention: they're like an American TARDIS for children.
