CNN is taking citizen journalism one step further with Open Stories, a collaboration between The Barbarian Group and CNN iReport.
It combines traditional CNN Reporting with user submitted 'iReports' (CNN has 750,000 active iReporters, on-the-ground reporters who often file stories before CNN broadcast journalists get to the scene). Open Stories threads them together to create a multi-faceted account of a single story, with contributors posting comments, video, photos and updates.
The project was announced at SXSW, and CNN is currently running an Open Story on the conference and festival. Check it out at the beta version of the site.
