While early techno-utopianists heralded the potential of the internet to challenge social hierarchies, most would concede that today’s digital media landscape is profoundly inequitable. Traditional markers of identity and inequality—including subjectivities of gender and femininity—persist online and are foregrounded across mainstream social media platforms like YouTube, Instagram, Pinterest, and TikTok. Against this backdrop, this chapter explores the ostensible feminization of various modes of social media labor, with particular attention to the cultures and practices of social media production and promotion (i.e., platformed content creation, digital entrepreneurship, social media management). To show how these activities are—much like earlier categories of “women’s work”—rendered socially and/or economically invisible, the authors examine four interrelated features of feminized labor: (1) the demand for emotional and affective expressions, (2) the discipline of aesthetics through the fraught ideal of “visibility,” (3) mandates for various kinds of flexibility, and (4) a deep imbrication with consumer capitalism. In exploring each of these features, the authors show how the patterned devaluation of gender-coded labor is exacerbated along other axes of oppression, including race, class, ethnicity, and sexuality. The authors conclude by calling for future inquiries into other cultures and expressions of social media labor, along with broader interrogations of platform visibility, vulnerability, and governance.
