Fast Culture, Slow Justice – How Digital Platforms Failed Black Lives Matter

In the summer of 2020, Black Lives Matter became the largest social movement in American history. As millions of people took to the streets, countless more went on Twitter, Instagram, Wattpad, and other online platforms to share stories, post images, and add their voices to a chorus demanding racial justice. It felt to many like a turning point. Why did this moment turn out to be so ephemeral?Drawing on social media posts, digital stories, and book reviews collected in real time, Richard Jean So uncovers the limitations of BLM as an online cultural phenomenon. Combining computational analysis with interviews and cultural critique, he reveals a fundamental contradiction at the heart of digital life: The very features that make platforms feel transformative—speed, emotional intensity, viral reach—are precisely what prevent movements from achieving lasting change. So shows how BLM’s online surge was shaped and ultimately constrained by platform logics that prize entertainment and pleasure, not accountability—and how a movement built by and for Black communities was rapidly co-opted by a flood of white liberal storytelling that centered feeling over social action. Fast Culture, Slow Justice transforms our understanding of digital activism and online culture, revealing not just what happened to BLM but why every social movement that routes itself through platforms faces the same structural trap.
