“…In contrast, the internet has been seen as offering citizens the opportunity to encounter and engage with a huge diversity of positions, thus extending the public sphere (Blumler and Gurevitch, 2001;Gimmler, 2001;Kellner, 2004;Papacharissi, 2002).Through email, discussion sites, web publishing and webcasting, a great variety of actors articulate and critique validity claims locally, nationally and internationally. However, those researching the possibility of the internet expanding democratic culture also point to significant factors limiting open and reflexive debate online, including inequalities in access and participation, unreflexive communication, corporate domination of online attention and state surveillance and censorship (Dahlberg, 2001(Dahlberg, , 2005bGomez, 2004;Hoar and Hope, 2002;Murdock and Golding, 2004;Wilhelm, 2000). Furthermore, a number of internet-democracy commentators question whether the myriad of diverse views that exist online are actually intersecting, and thus the extent to which online interactions actually involve any significant problematization and contestation of positions and practices.These commentators argue that much online interaction simply involves the meeting of 'like-minded' individuals, leading to a fragmented public sphere of insulated 'deliberative enclaves' where group positions and practices are reinforced rather than openly critiqued.…”
