ABSTRACT
This chapter presents an overview of key concepts discussed in the subsequent chapters of this book. The book presents the argument that the widespread utilization of networked communications technologies, especially social media applications, has brought forth new behaviors and relationships within liberal polities. Through the rapid and seemingly chaotic streams of networked communication, the actions of political and economic elites are subject to increasingly intense scrutiny. The same networked communications which allow the public to partially organize itself also enable elite actors to more strategically use the public for competitive advantage. The public reacts to statements made by opinion leaders and decisions made by elected officials. Sometimes, it seems as though there is a public reaction to everything, no matter how insignificant. All of these potential explanations hold some merit, yet none seem to fully represent the dynamic nature and significance of public reactivity.
