Facebook, Twitter and news organizations have joined a coalition of media and technology groups seeking to filter out online misinformation and improve news quality on social networks. First Draft News, which is backed by Google, announced that some 20 news organizations will be part of its partner network to share information on best practices for journalism in the online age. Jenni Sargent, managing director of First Draft, said the partner network will help advance the organization's goal of improving news online and on social networks. "Filtering out false information can be hard. Even if news organizations only share fact-checked and verified stories, everyone is a publisher and a potential source," she said in a blog post.
