How important online discussions (forums, social media, microblogging etc.) are in the process of shaping the public agenda and political participation? We have already know that media coverage affects peoples' perception about particular socio-political issues. Thanks to the media outlets one can deepen knowledge, fulfill the information gap and look "beyond the box" . Nevertheless, users comments are no less important. Interesting here is to what extent users' comments/opinions (malicious, substantive etc.) can affect the degree of political views and participation (particularly voting act) of other users? Does offended comments have more impact on that ? Does the spiral of silence still applicable? I'd love to know your opinions on that matter!
