Jürgen Habermas is a major figure in communication studies, political science, and sociology. One of his most important concepts is the role of discourse in the public sphere for sustaining democracy. His concept of the public sphere revolved around the growth of such media as newspapers, radio, and television. One obvious theme to investigate is how Habermas' model of public discourse can be applied to the web.
What makes a successful paper for a university class to show how Habermasian concepts would affect your analysis of a specific issue. You might discuss, for example, how one of the propositions on the California ballot was affected by internet campaigns or the role of the internet in Obama's campaign as reflections as exempla of political action in the public sphere.
