Times are changing, TV and radio are no longer the only and true source of information. The internet, and especially the social networks like Twitter, are becoming faster in delivering information and as influential as popular TV channels, or even more. Twitter was the first to publish information about the raid on Bin Laden. One of the users (Sohaib Athar, a.k.a. @ReallyVirtual) started tweeting, unaware what he was really describing.
His tweets gave a detailed story of the attack and death of the Al-Qaeda leader. Twitter also is a crucial part of the more recent events, like the unexpected storm in Pukkelpop (Belgium), English Riots or The Wall Street Protests. In most of these cases it was used by its users to help and update each other on the current situation. However, it happened that some users tried to make even bigger chaos and panic than the one already present.
