Among the many so-called microblogging services that allow their users to describe their current status in short posts, Twitter is probably among the most popular and well known. Since its launch in 2006, Twitter use has evolved and is increasingly used in a variety of contexts. This article utilizes emerging online tools and presents a rationale for data collection and analysis of Twitter users. The suggested approach is exemplified with a case study: Twitter use during the 2010 Swedish election. Although many of the initial hopes for e-democracy appear to have gone largely unfulfilled, the successful employment of the internet during the 2008 US presidential campaign has again raised voices claiming that the internet, and particularly social media applications like Twitter, provides interesting opportunities for online campaigning and deliberation. Besides providing an overarching analysis of how Twitter use was fashioned during the 2010 Swedish election campaign, this study identifies different user types based on how high-end users utilized the Twitter service. By suggesting a novel approach to the study of microblogging and by identifying user types, this study contributes to the burgeoning field of microblog research and gives specific insights into the practice of civic microblogging.

Populism continues to gain traction in politics but there has been relatively little research on how it plays out on the Internet. The special issue at hand aims at narrowing this gap of research by focusing on the close relation between populism and online communication. This introduction presents an integrative definition of populism, as well as a theoretical analysis of the interplay between populist communication logic and online opportunity structures. The individual contributions discuss how populist actors may benefit from the Internet. They analyze how political leaders and extreme parties use populist online communication. The authors also shed light on how populist movements may relate to various political parties. They finally demonstrate which groups of social media users are more susceptible to populism than others and what effects populist online communication may have on citizens. We hope that this special issue will contribute to the discussion on what is arguably one of the largest political challenges currently faced by a series of nations around the globe.

While plenty of research has provided important insights into the uses of the Internet by politicians during elections, a relatively scarce amount of work has looked into these uses outside of such parliamentary events. This article seeks to remedy this lack of research by presenting a study on the ‘routine’ uses of two of the currently most popular social media services – Facebook and Twitter. Focusing on politicians elected to the national parliaments of Norway and Sweden, the article employs novel methodologies for data collection and statistical analyses in order to provide an overarching, structural view of the day-to-day social media practices of Scandinavian politicians. Findings indicate that use levels are rather low for both services – the median amount of tweets sent and messages posted on Facebook is close to one per day. Further analyses reveal that the most active politicians could be labelled as ‘underdogs’, as they are more likely to be younger, in opposition and out of the political limelight.

News sharing across different social media platforms is increasingly impacting on our news habits. However, we know very little about what makes news popular in these settings. The current paper details what types of news stories are are shared the most on two social media platforms -Facebook and Twitter. By conducting a qualitative content analysis and comparing data from four Norwegian media outlets we find that editorial comment pieces about 'softer' news topics are more frequently shared than 'harder' news topics from all media outlets -except for TV2. For this latter broadcaster, the results suggest that sensational news and news regarding celebrities allows for viral effects to take place.

Many claims have been made regarding the influence of social media like Facebook on activities undertaken by political actors. While the study of online political communication provides several different perspectives, few studies have attempted to uncover tendencies of so-called permanent campaigning in online environments. The term signifies campaign-like activities at the hands of politicians also during nonelection periods and has spawned a number of conceptual discussions. This article presents an exploratory effort, studying traces of permanent campaigning in two similar countries-Norway and Sweden. As the former of these countries underwent a parliamentary election during the studied period, the study provides insights into "the election effect"-heightened levels of online activity among the Norwegian parties and politicians that can perhaps best be understood in relation to an ongoing election.
