This document discusses how YouTube serves as a platform for negotiating cultural and linguistic identities through user comments on videos. It analyzes comments on videos by East Asian pop stars singing in English, which provoked discussion of whether Asian singers can sing in English and express sexuality. The document argues that YouTube comments create a virtual space where identities can be negotiated across East Asia and its diasporas at a regional scale through English. It also examines comments on a video of a loud "Bus Uncle" in Hong Kong that invoke issues of Hong Kong, Chinese, and regional Asian identities and cultures.
