As feminist and anti-racist scholars and activists have long known, which stories predominate and which are marginalised is always a question of power and authority--about who is entitled to speak, and who has the authority to decide the meanings of words and actions. Storytelling can be used as a tool for social justice, as exemplified by the international feminist movement Hollaback! and its regional and worldwide struggle to end street harassment and make public spaces accessible for everyone. This article examines the practice of sharing stories within one specific Hollaback! group, highlighting the timeliness of the online storytelling technologies promoted by the movement and considering this work as an example of extra-academic feminist education. The article concludes by questioning to what extent feminists manage to formulate their own localised struggles through storytelling within the feminist movement as a whole.
