What is the anti-social media? It can be many things, but this particular study from the Demos group "aims to inform the discussion over free speech and hate speech by examining specifically the way racial, religious and ethnic slurs are employed on Twitter." This 51-page paper from February 2014 looks into how various terms are deployed on Twitter via in-depth analysis. It's quite fascinating as the team looks at a wide range of terms and also offers some substantial analysis of their findings and the possible broader implications of their work. For fans and critics of social media alike, this is a great trove of information.
