This chapter explores how architects of more recent Latin American counterpublics – particularly feminist, women’s, and queer organizations in Argentina, Mexico, and Brazil – have integrated the internet to support their goals of inclusion, community-building, and strategizing for social change. It focuses on the early experiences with the internet to capture that time of experimentation, exultation, and confusion, but also incorporates the advent of social media. Activists have struggled to confront how class, ethnic and racial inequalities, as well as workloads, are exacerbated by a new technology. Nevertheless, they have linked chains of access across their own digital divides; built community on the basis of low-cost services; and made an impact on national and international politics using a range of applications.
