U.S. President @BarackObama was the first world leader to open a Twitter account and has more followers than any other politician in the world (53 million, only marginally fewer than Justin Bieber). Ranked second among world leaders is Pope Francis (@Pontifex) with 16 million followers.
Despite his massive following, @BarackObama’s tweets are only retweeted 1,195 times on average, and Pope Francis (@Pontifex) is by far the most influential tweeter, with an average of more than 10,000 retweets of every post he writes in Spanish and 6,436 in English.
Anyone can tweet to a world leader, though only a select few reply. African leaders seem to chat with their followers the most. Rwanda’s President @PaulKagame is the world’s most conversational leader. 87% of his tweets are replies and he is always game for a spot of bickering on Twitter with his critics.
The most ingenious use of social networking as a tool for democracy is a phenomenon called ‘Participatory Budgeting’, an online way for citizens to decide how local government spends its money.
In the Dominican Republic, all the local governments allow the public to decide their budgets this way. This idea has spread to more than 1500 municipalities in Latin America, Europe, Asia, Africa, and North America to decide the budgets for their schools, universities, roads and public housing.
The first Participatory Budgeting scheme in the United States is in the 49th ward of Chicago, Illinois. Set up by the ward's alderman Joe Moore, it allows citizens to pick and choose from Joe Moore's ‘Menu Money.’
In 2009 ‘unfriend’ was the New Oxford American Dictionary Word Of The Year.
Every month, Americans use their mobiles to spend a total of 217 years on facebook.
