Obama: World's most popular president...of course on twitter

Now there is some good news for US President Barack Obama, he has left behind all the famous head of governements of the world, of course on the social site twitter. According to a survey of the social networking usage by heads of government, Obama was the first major politician to fully harness social media.

According to The Scotsman, the survey by U.S.-based PR firm Burson-Marsteller looking at the rise of "Twiplomacy", his Twitter account @BarackObama sent the most popular tweet of any world leader on 9 May.

However his account is ranked fifth in the Twitterverse for followers, just behind @britneyspears, according to the study. Venezuelan president Hugo Chavez - @chavezcandanga, is the second most popular leader on Twitter, and 38 per cent of his tweets are replies.

British Prime Minister David Cameron came fifth with more than two million follower among the other world leaders.

However, while Obama was top in terms of number of followers, only 1 percent of tweets from his account are replies, putting him well down the rankings in terms of engaging with his followers.

Like many government accounts, his team sent the vast majority of Obama's messages.

Only eight of the almost 5,000 tweets sent from the @BarackObama account were personally signed off with his initials "BO," including a Valentine's Day message to his wife.
