The Social Sharing of News - gatekeeping and Opinion Leadership on Twitter
Social media facilitate dissemination, sharing, curation, and modification of news. They contribute to evaporating earlier distinctions between news production and consumption. Citizens play an increasing role in these developments. This particularly takes place through the social network sites Twitter and Facebook, which have become meta media for personal contacts and wider societal agenda setting (Linaa Jensen & Tække, 2013). An increasing amount of news consumption is based on links and stories shared by friends, family, and colleagues. Alfred Hermida (2012) has termed these tendencies social sharing.
