Can social media increase and improve civic participation? If so, in what ways? There’s a lot being said and written about the subject these days, but it is difficult to get a clear overview of the opinions. I attempt here to collect viewpoints both for and against the premise that social media is creating a better public sphere, and analyze them in the context of what constitutes a public and its antithesis, a mass. In presenting what are sometimes extreme positions within this debate (too idealistic v. too critical), my hope is to begin to understand the reality that lies in the middle, and come closer to understanding social media’s potential (and limitations) as a tool to bring about social change.
