Research has established that access to the Internet and social media is vital for many lesbian, gay, bi, trans, queer + (LGBTQ+) young people. LGBTQ+ social media youth cultures form across platforms and are shaped by a range of media affordances and vernaculars. LGBTQ+ youth use social media for self-expression, connecting with other LGBTQ+ young people, entertainment, activism, and collecting and curating information. Through a digital cultural studies approach, the essay discusses themes of LGBTQ+ youth identity work, communities and networked publics, and youth voice to explore how digital and social media imaginaries and practices produce new forms of socialites. It situates LGBTQ+ youth social media practices in relation to the affective economy and algorithmic exclusion of platforms, as well as in relation to neoliberal paradigms of gender and sexuality and homotolerance.
