According to recent statistics, Saudis are the fastest growing group on the social networking website Twitter with an increase that amounts to 3,000 percent. Twitter is witnessing an unprecedented increase in its users across the Middle East in general, but Saudi Arabia ranks first with a 3,000 percent growth last month alone, said Twitter CEO Dick Costolo. “Twitter is seeing some of its most torrid growth in the Middle East. Saudi Arabia is the fastest-growing country with a 3,000 percent growth last month,” he told The Los Angeles Times. Costolo added that Twitter has 140 million active users, mainly based in the U.S., the UK, and Japan. “Of the 140 million active users, 25 to 30 percent of them are in the U.S.,” he said. “U.K. and Japan are Twitter’s No. 2 and No. 3 countries, respectively.” Half of those active users, he explained, log in every day while more than half access Twitter via their mobile phones. This percentage increases remarkably in the UK and Japan where 75-80 percent use their mobile phones to access Twitter. Costolo noted that it took Twitter three years and two months to reach one billion tweets, yet this same number only takes two-and-a-half days to reach. “Now 400 million tweets are sent a day. It takes two-and-a-half days to send 1 billion tweets.”  text he
