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).

This is an event-based process of community formation which leads to a gradually strengthening cohesion of community activities that generates impact and finally results in stasis. In this, overlapping virtual and physical communities are embodied in a wider imagined community …

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.

The grieving online following Houston's death can be understood as ritual – there was no documentation of news, but a reflection on who we are, how we express …

The final presenters in this AoIR 2012 session are Camila Monteiro, Raquel Recuero, and Adriana Amaral, who begin by noting the demographics of Twitter in Brazil: there are some 33 million Brazilian Twitter users, most of whom are adolescents. Their interest in this paper is especially in fandom and anti-fandom around the pop band Restart, and in the social capital which such activities create and maintain.

Many of the trending topics in Brazil are focussed on popular music, in fact, and fans seem to artificially attempt to create such trending topics. The researchers engaged in interviews with fans as well …

Next up at AoIR 2012 it's Tim Highfield and me again, presenting a paper co-authored with our colleague Stephen Harrington. Here are the slides; audio to follow. and audio.

#Eurovision: Twitter as a Technology of Fandom from Axel Bruns

My colleagues and I have a paper in the next session at AoIR 2012, too, but we start with Rachel Magee, whose interest is in fandom on Twitter around the recent movie The Hunger Games. She and her colleagues developed the Twitter Zombie system, which draws on the Twitter search API to track user and hashtag activity around he movie. The movie is based on a popular novel for teen audiences, and the film itself was also very successful, with substantial fan activities around it.

In anticipation of the movie, there was significant Twitter activity - Rachel and …

The first AoIR 2012 session this Saturday starts with my paper with my colleagues Tim Highfield and Stephen Harrington, which presents our work on the Australian Twitter New Index (ATNIX). Below are the slides – for more, also see my column at The Conversation. Audio to follow soon! I've added the audio now, too.

Sharing the News: Dissemination of Links to Australian News Sites on Twitter from Axel Bruns

The next speaker at this AoIR 2012 session is Dan Mercea, whose work stems from an interest in the Occupy movement in the Netherlands. Activity peaked in October 2011 with a series of marches and the establishment of Occupy camps, but gradually dwindled thereafter; social media played a prominent role in the initial organisation of these activities, reaching politically unaffiliated (potential) participants.

Social media may play two roles in this context: bridging and bonding participants. Twitter is primarily useful for creating bridges between a variety of participants, for example, while Facebook seems more conducive to both bridging and bonding; this …

Up next at AoIR 2012 is Zizi Papacharissi, whose focus is on structures of affect and their connection to political engagement. What is the texture of feeling here – for example in the expression of sentiment on Twitter? In her talk here, Zizi will focus on the #egypt hashtag.

Twitter is a form of news storytelling here, presenting collectively prodused newsfeeds which interact with the wider news economy; it can be an alternative or a primary channel for information. As a news reporting mechanism, Twitter can also offer premediation for news events which have not yet happened, or act …

And I've arrived at the 2012 Association of Internet Researchers conference – my annual pilgrimage to catch up with the family. We start with a quick burst of Ignite talks, which itself begins with John Carter McKnight. He notes the two fundamental axioms of video games studies: games teach, and games don't teach. The Red Cross has posed the question: Is there a way for first-person shooter games to include a more accuracy representation of international humanitarian law? Such laws are not especially firm, of course - much different from the rules in video games, which are more like gravity …
