The growth and popularity of social media throughout 2011 has not shown signs of slowing down, either on a global level or within the Arab region. Globally, Facebook still dominates, with over 800 million users worldwide, of which 50% log in daily, while 350 million users access Facebook through mobile devices2 . Twitter, on the other hand, reached over 100 million “active users” in September 20113 , with an estimated 200 million “tweets” generated each day. Half of these active users log in every day, although not all of them tweet. About 40% of active users log in just to get news.
