There is an ongoing academic debate whether social media empowers activists and advocacy groups in relation to established political actors and media gatekeepers. This article investigates these premises by analysing the influence of various actors in two policy debates on Twitter, environmental policy (climate change) and Internet governance (net neutrality). We extract tweets on both topics and code the respective 500 most central accounts according to a categorisation of relevant political actor groups. Applying methods from social network analysis, we reveal temporally fluctuating actor constellations and network structures which converge to elite actors during high attention periods. Furthermore, a comparative keyword analysis shows that non-governmental organisations and citizen media emphasise personalised connective action frames, whereas political actors and traditional media tend to refer to the political decision-making process and its institutions. Both findings are in line with cyclical conceptions of policy processes.

In 2013 Edward Snowden's disclosures of mass surveillance performed by US intelligence agencies seriously irritated politicians and citizens around the globe. This holds particularly true for privacy-sensitive communities in Germany. However, while the public was outraged, intelligence and security cooperation between the United States and Germany has been marked by continuity instead of disruption. The rather insubstantial debate over a so-called "No-Spy-Agreement" between the United States and Germany is just one telling example of the disconnect between public discourse and governmental action, as is the recent intelligence service regulation. This article considers why and where the "Snowden effect" has been lost on different discursive levels. We analyze and compare parliamentary and governmental discourses in the two years after the Snowden revelations by using the Sociology of Knowledge Approach to Discourse (SKAD) to dissect the groupspecific statements and interpretive schemes in 287 official documents by the German Bundestag, selected ministries and agencies within the policy subsystem. These will be analyzed in reference to actual governmental practice.

The internet has been seen as a medium that empowers individual political actors in relation to established political elites and media gatekeepers. The present article discusses this "net empowerment hypothesis" and tests it empirically by analysing Twitter communication on the regulation of net neutrality. We extracted 503.839 tweets containing #NetNeutrality posted between January and March 2015 and analysed central developments and the network structure of the debate. The empirical results show that traditional actors from media and politics still maintain a central role.
