The proliferation of social media has given rise to widespread study and speculation about the impact of digital technologies on politics, activism, and social change. Key among these debates is the role of social media in shaping the contemporary public sphere, and by proxy, our democracy. Maligned by some as “slacktivism,” it will be argued that social media platforms such as Twitter created unique opportunities for traditionally excluded voices to challenge the terms of public debate. Using the evidence from Twitter hashtag networks such as #BlackLivesMatter and #MeToo, we will demonstrate how hashtag activism complemented other forms of activism and changed the terms of mainstream discussions about race and gender justice in the United States. We will also reflect on the continued capacity of social media for social change, in light of recent changes to Twitter and other platforms.

This talk draws on research from #HashtagActivism: Networks of Race and Gender Justice, available for free through MIT Press Direct:
