My own paper starts the ICA-flavoured session at ECREA 2012 this afternoon; my presentation built on our research into the uses of Twitter to explore how we might reconceptualise the public sphere. The slides are below; audio will follow. now online, too.

Social Media, Big Data, and the Public Sphere from Axel Bruns

The final speaker in this AoIR 2012 session is Sheetal Agarwal, whose focus is also on Occupy-related Twitter networks. Is Occupy a networked organisation, and if so, what kind of networked organisation? How might its organisational features be assessed? There are plenty of theories about organisation, from organisational sociology to political economy, which have been applied to the study of communication networks, international relations, and digital media.

The next speaker at AoIR 2012 is Sky Croeser, co-presenting with the very busy Tim Highfield. Her focus is on Occupy Oakland, a subset of the overall Occupy movement, and its use of the #oo Twitter hashtag. Occupy Oakland is shaped by the radical history of Oakland – the Black Panthers emerged here, and there have been more recent public protests in the city as well.

The next session at AoIR 2012 starts with a paper by my colleague Tim Highfield that Stephen Harrington and I contributed to as well – he's focussing on Australian politics on Twitter. (Slides and audio to follow.) Here are the slides and audio; my notes on the presentation are below.

The next session at AoIR 2012 begins with a paper presented by Julian Ausserhofer and Axel Maireder about national politics on Twitter, in the case of Austria. Twitter is now being used by a range of political actors in the country, including journalists and politicians, who are at times publicly interacting with one another using the platform. Many users also link to news media materials, of course.

The final paper in this session at AoIR 2012 is by Elycia Taylor, whose focus is on the reaction to the 2012 Grammy win by Chris Brown, who had assaulted his partner, the singer Rihanna, following the 2009 Grammys. Brown had become a persona non grata at the time, but has made a recent comeback, and many of his new fans appear to be prepared to overlook this violent history. There are also rumours about Brown and Rihanna working together again.

The next speaker at AoIR 2012 is Jenny Korn, whose focus is on the #FuckProp8 hashtag which emerged around the Californian referendum to ban gay marriage, known as Proposition 8. The success of this referendum was a surprise to many Californians themselves, and resulted in a substantial amount of pushback, in the form of the hashtag (and its alternative #rejectprop8).

The next session at AoIR 2012 starts with Catherine Knight Steele, whose focus is on the online expression of grief following the death of Whitney Houston. Many of the messages being posted following her death seemed more like the support offered to family members than a public expression of fandom. The same was not true in the same way following the death of Michael Jackson, when many more critical responses were aired.
