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.

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 second speaker in this AoIR 2012 session is Lucy Morieson, whose focus is also on Australian online news – in particular, on the Websites of The Age, Crikey, and The Conversation. This also plays out against the changing business and professional environments for Australian journalism, of course.

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

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.

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:
