Selfie sticks, the logical "extension" of an already irksome activity, were recently banned in Premier League soccer stadiums. Now museums around the world are starting to do the same over worries of accidental damage to artwork. The Smithsonian barred their use effective last week as a "preventative measure to protect visitors and museum objects," especially on crowded days. Meanwhile, a formal ban is pending at Versailles palace and Centre Pompidou in France, and visitors are now being told to stow their sticks by guards at the Louvre. Both Pompidou and the Louvre will continue to allow regular photography and selfies.
