New York Times: Who’s on the Line? Increasingly, Caller ID Is Duped Telemarketers are faking Caller ID information with apparent impunity, so that people believe that the IRS or the FBI is calling. (Just like spam!) The FTC has just filed their first complaint against a company for doing that. The FCC wouldn't comment as to what they're doing about it.
Wikipedia: List of nicknames of United States presidents John Tyler, Rutherford B. Hayes, Warren G. Harding, and Richard Nixon are the only former U.S. presidents who did not have a (non-derisory) nickname as president. ("Tricky Dick," for instance, doesn't make the cut.) President Obama does not yet have a nickname and, given how unusual his name is, I suspect he won't get one. The heyday of nicknames was the early 20th century, when a few popular given names reigned supreme—when three friends are all named "Michael," nicknaming is inevitable. The most popular names today are far less common than a century ago, making nicknames linguistically unnecessary.
