An hour before the official annoucement of Osama Bin Laden’s death Keith Urbahn, a 27 year old chief of staff for former defense secretary Donal Rumsfeld tweeted “”So I’m told by a reputable person they have killed Osama Bin Laden. Hot damn.” The speculation about an important announcement was already set in motion in Twitter and many before Urbahn were speculating about what it could be. Some had guessed correctly that Osama Bin Laden had been killed. This created an attentive crowd so when Urbahn, a chief of staff, tweeted with such authority the message spreaded quickly. Among the people that re-tweeted the message was New York Times reporter Brian Selter giving the tweet more value and making it trustworthy.
