This NY Times piece on the pre-announcement editing of Sarah Palin's Wikipedia entry sheds light on the way Wikipedia functions in the larger media ecology, in large part based on its open structure and currency. That updates in the wee hours prior to a candidacy announcement might be the efforts of an insider comes as little surprise. But the way that such updates morph the site into a kind of engine for dissemination and creation of news shows that the combination of at-large editing and instant updating amplifies information sharing power enough that people need to adjust their expectations about where to find (and how to make) the news. As the Times reports, the Washington Post called it "another example of Wikipedia’s mysterious ability to predict about-to-break news, if we only knew to look there."
