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.

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.

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.

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.

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?

Well, as Tuesday's blogburst already indicated, I'm slowly progressing on my current travels. The event at the Copenhagen Centre for Communication and Computing was something of a preview for a panel on "Digital Data – Lost, Found, and Made" which is on the programme for the 2012 conference of the Association of Internet Researchers here in Salford; expect plenty of liveblogging from that conference to start tomorrow.

Before this conference and the Copenhagen event, though, I spent a few days in Helsinki, where I gave two guest lectures in the international Masters course – and I've neglected to post those lectures here so far. So, here they are. Unfortunately, my audio recorder ran out of batteries during the first lecture, so there are only slides for it - however, that lecture was a repeat of my SBPJor keynote in Brazil last October, so you can go to those slides for the audio.

Below are the two lectures:
