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.

Social flow has an incredible visual and written analysis on how a single tweet had a massive effect on the newsworld.

Biz Stone is one of Twitters founders. In the following article he discusses the role of Twitter in journalism.

The news applications surprised us… We noticed in prototypes early on, though, that things like earthquakes led to Twitter updates. The first Twitter report of the ground shaking during recent tremors in California, for example, came nine minutes before the first Associated Press alert. So we knew early on that a shared event such as an earthquake would lead people to look at Twitter for news almost without thinking.

Andy Carvin is a senior strategist at NPR. During the protests in Tunisia and Egypt he used his twitter account as a personal news wire. He seeked out sources in Egypt and shared them over his account. He collected tweets and Facebook messages, curated and publish them afterwards. His followers on Twitter helped him by translating and researching questions. The result was a collection of first hand accounts that were published not only via his Twitter account but also by fellow journalists. Articles here and here

In February, five journalists from French-speaking public radio stations isolated themselves in a farmhouse in southern France to conduct an experiment. For five days they would stay informed by using only their social networks. Their ground rules forbid them to follow the feeds and tweets of any news media; to be informed, they had to rely solely on the tweets or Facebook offerings of individuals or organizations such as nonprofits, government agencies, or educational institutions. One of the secluded journalists was reporter Janic Tremblay, who works at Radio-Canada. In this article, he describes the experience and the lessons he brought back to his work.

Citizen Media

The term citizen media refers to forms of content produced by private citizens who are otherwise not professional journalists. Citizen journalism, participatory media and democratic media are related principles.

Citizen Journalism

Citizen journalism (also known as “public”, “participatory”, “democratic”, “guerrilla”or “street journalism”) is the concept of members of the public “playing an active role in the process of collecting, reporting, analyzing and disseminating news and information,” according to the seminal 2003 report We Media: How Audiences are Shaping the Future of News and Information. Authors Bowman and Willis say: “The intent of this participation is to provide independent, reliable, accurate, wide-ranging and relevant information that a democracy requires.”
