Protest leadership in the age of social media

Thomas Poell; Rasha Abdulla; Bernhard Rieder; R. Woltering; L. Zack

ABSTRACT This article challenges the idea that social media protest mobilization and communication are primarily propelled by the self-motivated sharing of ideas, plans, images, and resources. It shows that leadership plays a vital role in steering popular contention on key social platforms. This argument is developed through a detailed case study on the interaction between the administrators and users of the Kullena Khaled Said Facebook page, the most popular online platform during the Egyptian revolution of early 2011. The analysis specifically focuses on the period from 1 January until 15 February 2011. It draws from 1629 admin posts and 1,465,696 user comments, extracted via a customized version of Netvizz. For each day during this period, the three most engaged with posts, as well as the 10 most engaged with comments, have been translated and coded, making it possible to systematically examine how the administrators tried to shape the communication on the page, and how users responded to these efforts. This analysis is pursued from a sociotechnical perspective. It traces how the exchanges on the page are simultaneously shaped by the admins’ marketing strategies and the technological architecture of the Facebook page. On the basis of this exploration, we argue that the page administrators should be understood as ‘connective leaders’. Rather than directing protest activity through formal organizations and collective identity frames, as social movement leaders have traditionally done, connective leaders invite and steer user participation by employing sophisticated marketing strategies to connect users in online communication streams and networks.

Data critique and analytical opportunities for very large Facebook Pages: Lessons learned from exploring “We are all Khaled Said”

Bernhard Rieder; Rasha Abdulla; Thomas Poell; R. Woltering; L. Zack

This paper discusses the empirical, Application Programming Interface (API)-based analysis of very large Facebook Pages. Looking in detail at the technical characteristics, conventions, and peculiarities of Facebook’s architecture and data interface, we argue that such technical fieldwork is essential to data-driven research, both as a crucial form of data critique and as a way to identify analytical opportunities. Using the “We are all Khaled Said” Facebook Page, which hosted the activities of nearly 1.9 million users during the Egyptian Revolution and beyond, as empirical example, we show how Facebook’s API raises important questions about data detail, completeness, consistency over time, and architectural complexity. We then outline an exploratory approach and a number of analytical techniques that take the API and its idiosyncrasies as a starting point for the concrete investigation of a large dataset. Our goal is to close the gap between Big Data research and research about Big Data by showing that the critical investigation of technicity is essential for empirical research and that attention to the particularities of empirical work can provide a deeper understanding of the various issues Big Data research is entangled with.

Facebook polls as proto-democratic instruments in the Egyptian revolution: The ‘We Are All Khaled Said’ Facebook page:

Rasha Abdulla; Thomas Poell; Bernhard Rieder; R. Woltering; L. Zack

This article examines the dynamics of political participation on the ‘We Are All Khaled Said’ Facebook page, which hosted the call for Egypt’s 25 January 2011 revolution. It shows that the page served as a proto-democratic instrument by introducing both qualitative and quantitative polls and following up with actions based on majority opinion. This argument is developed through an analysis of discussion threads and polls from the page, selected from a data set of 14,072 posts, 6,810,357 comments and 32,030,731 likes made by 1,892,118 users, extracted via a customized version of Netvizz. The analysis demonstrates that the page provided a basic lesson in democratic participation to its users. ‘We Are All Khaled Said’ constituted an unprecedented public space for active discussions on fighting corruption, torture and police brutality. Moreover, it served as a practical example of shared governance and political participation, which became a model for its users to strive to apply to their country.
