'Three points will make this volume a strong contribution to the sociolinguistics of youth identities in the twenty-first century: its inclusive approach to structure, practice and ideology as closely intertwined dimensions of linguistic study; its coverage of a broad range of languages, communities, and communicative contexts; and the comparative design of the individual chapters, which reveal fascinating, and sometimes unexpected, patterns of similarity and contrast.'
