Gothenburg.
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, politics and world affairs, media and culture, products and services). Twitter debate is also connected heavily with mainstream news media sources – URLs to mainstream content are widely distributed (and make up some 40% of distributed URLs). This means that Twitter users who distribute such content act as intermediaries between mass media content and their fellow users. Of those URLs, some 60% link to sources which advocate specific points of view.
