US President Barack Obama has topped the league of world leaders with 17 million followers on Twitter, according to a survey of the social networking usage by heads of government.
This compares with Rwandan President @PaulKagame, who has just under 71,000 followers, but whose tweets are more than 90 percent replies. 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.
The study also found that politicians frequently discover Twitter during election campaigns, but once elected the accounts fall silent.
He also ranked the sixth most popular world leader who "tweets properly" -- coming in at number 30 out of 254 head of states and government that actually do their own tweeting.
Najib started to tweet on Sept 23, 2008 and as of today he has 767,679 followers on Twitter with 2,675 tweets and 81 following.
This makes him by far the most popular national leader in Asia on Twitter, per capita (1 in 37) and comfortably in the global top ten.
According to the report, Najib is also following a number of international and regional leaders and is mutually connected with @bluehousekorea, @karimmassimov_e and @number10gov.
