The second ECREA 2012 keynote speaker this morning is Clemencia Rodríguez, who will be shifting our focus further towards citizens' media. She notes that it is important to take historical precedents seriously – reacting against the popular representation of recent political unrest as driven and determined by social media, and as leaderless revolutions.

From the excitement of a thoroughly inspiring AoIR 2012 conference, I've now made my way to Istanbul for this year's European Communications Conference, ECREA 2012. We open the conference with a keynote on e-democracy by Donatella dells Porta, considering the types of democracy which new social movements are envisaging.

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 third speaker in this AoIR 2012 session is Sharon Strover, who begins by noting a racist YouTube video which complained about Asian students in the UCLA library and rapidly generated a substantial number of response videos; this can be seen as a form of civic engagement which must be distinguished from political participation.

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 final speaker in this panel at AoIR 2012 is Delia Dumitrica, whose interest is in how citizens conceptualise the use of social media in political communication. Her premise is that this can be understood as an attempt to discursively articulate wider issues of trust in politicians.

The second presenter in this session at AoIR 2012 is Sander Schwartz, who shifts our attention to the use of social media during the 2011 Danish election. His project drew on a panel of 6,000 volunteers whose Internet use was monitored, as well as on a survey of some 2,000 respondents from this group. The panel was representative of the wider Danish population; the survey group was self-selecting.

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.
