As they say in social media, feminism is "trending"; feminist conversations, grassroots movements, and activism mark a fourth wave of feminist practice and theory defined by digital spaces. This article considers the effectiveness of using social media as both a course assignment and as a conduit for civic engagement. I analyse survey results of college students who used the blogging platform Tumblr in their "Introduction to Women, Gender, and Sexuality Studies" courses. Data collected from the participant sample indicate that Tumblr users are connected to viewpoints different from their own and are instilled with a sense of activism they wish to incorporate in their offline lives. In conclusion, social media is a promising tool for social justice, feminist, and/or leadership-focused praxis.
