The next speaker in our social media mapping panel at AoIR 2010 is Hallvard Moe, whose focus is on Twitter as an arena for public debate in Norway, around the data retention policy debate in that country. Norway is traditionally a social-democratic state with relatively advanced use of ICTs, apparently including some 160,000 Twitter users; this also meant that there was substantial debate about the adoption of the EU data retention directive (for regularly archiving phone and network data).

Hallvard archived tweets on the #dld hashtag using Twapperkeeper, between April and early August 2010, resulting in some 12,000 …

My own paper (with Jean Burgess, Thomas Nicolai, and Lars Kirchhoff) starts the final session of this second day at AoIR 2010. Below is the Powerpoint, and I’ll try to add the audio some time soon the audio is online now, too.

The next speaker at AoIR 2010 is Theo Plothe, whose interest is in the use of Twitter by NFL players in the US. The NFL is the most popular league in the US, and players are increasingly participating in it – presumably also encouraged by their employers. NBA player Charlie Villanueva, in fact, was reprimanded for tweeting during a basketball game. NFL players have also been fined, suspended, and fired for tweeting inappropriate comments – and in fact, player Ocho Cinco even orchestrated a post-touchdown celebration with fans via Twitter.

The next AoIR 2010 speaker is David Houghton, whose interest is also in Twitter. He starts by pointing to a range of tweets of varying degrees of mundaneness and secrecy, and is interested in examining linguistic differences in them. What threats to personal privacy result from the spread of gossip? How can levels of self-disclosure be measured – in breadth or depth, for example – in order to alert users to when they might be compromising themselves by oversharing?

How do we enable users to go about sharing while protecting their concerns and informing them about potential harms …

I must admit I missed the 8.20 a.m. sessions this morning – just couldn’t cope with the cold. So, we’re jumping right into the next session at AoIR 2010, which starts with Axel Maireder. He begins by noting the function of Twitter as a medium for public discourse; tweets can reach large audiences especially if retweeted widely (an average of 1000 users for each retweet).

Twitter is used for debate on public issues, of course – and Axel’s study has identified a number of typical themes (education and professional, spare time, everyday life, social relations, mottos and aphorisms …

My own paper was next at ECREA 2010. Here’s the presentation – and I also recorded the audio for it, and will add it as soon as I can which is now attached to the slides. As it turned out, one of the other presenters in the session also broadcast the whole event to Justin.tv – so go there to see it all in action (my presentation starts around 52 minutes in, and you can also see the other papers on our panel)…

The next speaker at ECREA 2010 is Jonathan Hickman, whose interest is in #hashtags on Twitter. Hashtags are a simple way for Twitter users to organise their conversations, by putting the ‘#’ symbol in front of words to make tweets on specific topics more easily searchable (e.g. #iranelection). The hashtag is a form of metadata in that it describes the content of the tweets. This is part of a wider practice of tagging in computer-mediated content; tags are widely used for a wide variety of online materials.

However, there are also problems with this, as these tags are …

The next speaker at ECREA 2010 starts with Jennifer Jones, whose focus is also on Twitter: she was an embedded journalist at the Vancouver Winter Olympics. There is a significant historical connection between the Olympic Games and technology, and new media have been especially prominent in recent years; there has been substantial growth especially in alternative media coverage (by non-accredited journalists and others). In Sydney, there even was an alternative media centre for the Olympics.

Independent media were prominent in Vancouver, too – people set up their own media centres, and printed their own unauthorised media passes, which …

The next session at ECREA 2010 is the one I’m in as well – but we start with Stine Lomborg, whose interest is in relationality on Twitter. This build on my concept of produsage, and examines this especially for the case of mundane, ordinary conversational activities. To engage in such communication, Twitter users must establish networks with each other – but such networks are non-symmetric, as followees won’t necessarily always follow back. This creates a particularly interest network structure.

Stine examined the activities of six Danish Twitter users, and captured their tweets and @replies over the course …
