What happens when a woman goes online? She becomes a girl. The unwritten contract of the internet, that a user is what is used, extends from the well-examined issue of data privacy and consent to the very selves women are encouraged to create in order to appear. Invited to self-construct as “girls online,” vloggers, bloggers and influencers sign a devil’s bargain: a platform on the condition they commodify themselves, eternally youthful, cute and responsibility-free, hiding offline domestic, professional and emotional labour while paying for their online presence with “accounts” of personal “experience.” Told via the arresting personal narrative of one woman negotiating the (cyber)space between her identities as girl, mother, writer, and commodified online persona, Girl Online is written in a plethora of the online styles, from programming language to the blog/diary, from tweets to lyric prose, taking in selfies, social media, celebrity and Cyberfeminism.
