Are you a Twitter user and/or interested in what world leaders are tweeting? Check out the the fascinating Twiplomacy website.
"Twelve world leaders have seen some of their tweets retweeted more than 20,000 times" in 2014, including "Queen Elizabeth's first personal tweet opening an exhibition at the Science Museum" and "the abdication tweet of the King of Spain," according to Twiplomacy Study 2014.
Another interesting tidbit: "Spanish is the most tweeted language" among world leaders.
(I'm not a world leader, but you can follow me on Twitter, too.)
