The final speaker in the ASMC14 session is Axel Maireder, whose focus is on the structure of the Twittersphere surrounding the recent European Union election. His approach is to examine the follower networks of participants in relevant discussions, and to explore which factors explain their structural patterns – such as shared national and language identity, political ideology, or other factors.

The study captured all tweets containing keywords such as European Parliament, European Election, and relevant hashtags (in the various European languages), and gathered tweets from some 440,000 users in total. Filtering these to users with at least two tweets and at least 250 followers resulted in some 11,000 core users who were retained for the network analysis.

Up next at ASMC14 is Jacob Ørmen, whose interest is in the processes of news engagement. News has always been conveyed to others through many different channels, importantly also including ordinary political conversations between everyday people. Social media and similar sites facilitate such conversations, but this also needs to be placed in a wider context that also recognises other such conversations.

In which situations, then, do people engage in such conversations about politics? When and where do they do so? Jacob has examined this for the case of Denmark, where political engagement generally is fairly strong; Danes generally like to talk about politics, but do not necessarily do so online. Jacob's approach to researching this has used surveys and interviews to explore how people choose their spaces for political discussion.

He has defined a number of types: mixed sharers, who talk face to face, but mostly on social media; conversationalists who mainly use face to face; news consumers who receive but do not discuss political news; and disengaged citizens. Conversationalists and news consumers receive information via face to face, email, SMS, phone, and social media, but do not themselves further the discussion through electronic media forms; conversationalists tend to be older or of school age, while mixed sharers are largely early to middle-aged adults.

The second speaker in this ASMC14 session is Edoardo Novelli, whose interest is in the online activities around the recent election of the Italian President. While the President was elected by members of parliament, a great deal of alternative direct democracy activities took place online, driven especially by the Cinque Stelle movement of Beppe Grillo.

Edoardo conducted an analysis of social as well as mainstream media activities around the election, gathering data from newspapers and television, Internet and social media. During the election, the Net was used by various actors for official and unofficial forms of communication. This caused a change in the traditional flows of information and diffusion across a hybrid news system, impacted on traditional political communication practices, and allowed for the emergence of grassroots voices.

Largely, the Net has been used by parties and politicians for official and political communications. Cinque Stelle ran an online poll of its members as an alternative election to that of the President; important political meetings were broadcast live, and thereby turned into performances; Twitter was used very widely to convene demonstrations; social media were used to comment on events during the election process; political leaders were taking directly to social media to bypass conventional communication channels; party Websites and politican blogs also played a role.

The next session at ASMC14 starts with Eirik Vatnøy, who takes a rhetorical perspective in his approach to Twitter. Social media are an arena for political debate, but how do they change the norms and praxis of political rhetoric? Eirik interviewed Twitter users who engaged in continuous political debate on the platform.

Rhetorics considers the public sphere as a reticulate public sphere (made up of many smaller spheres), and this applies to Twitter as well. Actors recognise the discursive and social norms which uphold such spheres, and a combination of quantitative and qualitative analysis of communicative activities can help to explore these norms. However, this is a complex challenge, as different users may use the various affordances of Twitter as a platform in different ways.

Eirik interviewed 18 users, chosen through snowball selection; they included active politicians, editors, journalists, bloggers, communication workers, lawyers, etc. Interviews were structured around key themes including perceived affordances, toles and relations, discursive norms, and social norms.

The final keynote at ASMC14 is by the fabulous Hallvard Moe, whose focus is on the intersections between social media and public service broadcasting. How can media researchers contribute to rethinking public service broadcasting? Defining PSB is difficult, but there is often a belief that policy makers know it when they see it; PSB is an inherently contested concept, coined a very long time ago in a very different context – even in Europe alone, how PSBs are positioned and organised is very different across different countries.

What such institutions have in common, though, is the general aim that PSBs should provide vital information and contribute to the public good; they are a policy tool to provide journalism and bring citizens together as a public. PSB institutions around the world do not necessarily always achieve such an ideal – they now exist in almost constant turmoil, due to a range of contextual factors. They can only survive by externalising their internal challenges; these challenges are always present, and in recent years especially associated with the rise of digital media and the media practices such media enable and promote.

The final speakers in the ASMC14 session is by Tamara Witschge and Mark Deuze. Tamara begins by noting her skepticism about the current state of journalism, and highlights the fact that many journalists are highly reluctant to work as freelancers outside of the conventional newsroom – yet those journalists who do work as freelancers often say that they would not go back to an institutional setting.

This is a question relating to the social dimension of news production, of course. New models challenge the conceptualisation of what is news, who produces it, and what it is for; new news startups show remarkable passion and innovation in rethinking the idea of news, and do not necessarily work with conventional conceptualisations of journalism. Tamara's and Mark's project aims to gain insight into such new organisations.

The third speaker at this ASMC14 session is Paolo Gerbaudo, whose interest is in the organisational processes of informal collaboration in social media activism. In order to understand these processes it is not enough to study the large datasets of their outputs, but to also ask the people behind such activities why and how they do this work.

Across the various cases of social media activism in recent years there has been a clear power distribution – a handful of leading accounts have been driving protests such as Occupy, Indignados, or the Arab Spring. These accounts have attracted a large number of followers and serve as movement leaders and organisers. Who is behind these accounts; who is working to keep such feeds going, and how?

The next ASMC14 speaker is Heather Ford, who shifts our focus to Wikipedia. In its early days, the site was seen as an underdog challenging existing publishing models – this includes news publishers, and Wikipedia was seen as a challenger to the conventional gatekeepers. It was also shown that the quality of its content was not necessarily any worse than that of traditional encyclopaedias, even though it had been collaboratively compiled. Nonetheless, a persistent view of its inaccuracy due to this collaborative model remains.

Wikipedia itself offers a range of self-definitions, which inter alia point out that Wikipedia is not a social network (or even a dating service), so personal profiles should be kept short; not a soap box from which to promote personal views or original research. Wikipedia also defines reliable sources which should be used as evidence for its articles, and in doing so for the most part explicitly rules out self-published media (blogs, etc.) as unreliable.
