ABSTRACT
This chapter considers Twitter as a networked communication space that results in a mixture of old and new frames, values, and approaches, particularly at times of breaking news. It examines the dynamics of professional news practice on the social media platform and considers how far new, fluid forms of journalism are at play. The chapter also considers the relationship between Twitter and journalism through the prism of the profession. A process of negotiation between the old and the new has marked the use of Twitter in journalism, the result of the affordances of new media technologies bumping up against established practices. Research on the hyperlinks related to social movements illustrates how secondary gatekeeping shapes the circulation of the content on Twitter. Gatekeeping has been a central construct in journalism. Editorially, the traditional gatekeeping function of the media has been weakened by the rise of social recommendation, introducing hybridity into gatekeeping.
