Examining how Latinx identity reimagines and connects communities through social media. The very idea of Latinidad flattens identities, subsuming diverse peoples under a single racialized framework useful for corporate and political marketing. But it is not only ethnic identity that Latinidad tends to erase. In the first-ever study of Latinx social media, Urayoán Noel shows how historically marginalized Latinxs--including Black, Trans, undocumented, and disabled people--have used digital platforms to challenge hegemonic Latinidad and to build alternatives communities. Incorporating elements of history, ethnography, and performance studies, Virtually Latinx traces the evolution of Latinx social media and blogging since the early 1990s, focusing on creative movements and vocabularies emerging and consolidating online. From Chicano/LatinoNet, Latina Lista, and Remezcla, to activists and performers on TikTok, online creators and platforms have spurred modes of art and activism that counter both Latinidad's essentialized body politics and Big Tech's domination of the information sphere. In dialogue with scholars of media, virtuality, and identity, Noel theorizes how hashtags like #Afrolatina, #Latinx, and #Latine have not only facilitated online exchange but also nurtured new knowledge formations surrounding Black, feminist, undocuqueer, Trans, and disability poetics and politics.
