Hi members I am currently supervising a PhD student who is examining how pressure groups like NPOs get their talking points into the mainstream media and public domain through using social media, especially Twitter. I was hoping members could provide some guidelines on useful literature to frame this discussion. The student is looking at public spheres and networked publics, but this seems not to engage sufficiently with the idea of actively strategizing around constructing messages to be taken up by the public. I was hoping there is literature that takes theories of agenda setting and influence/persuasion into the social media realm. I will really appreciate your suggestions.
