The next presentation at AoIR 2009 is by Hallvard Moe, who begins by noting that the public sphere is still a useful concept It exposes us to expressions, opinions, and perspective we would not otherwise have chosen in advance, and provides a range of common experiences for citizens. But how do online media impinge on this - do they segment and polarise the public sphere (as suggested by people like Cass Sunstein), or provide more connections between and access to different ideas (as per Yochai Benkler's networked public sphere)?
