Contemporary movements of people and resources across rural and urban settings, city locales and national and regional borders produce challenges for familiar ways of studying languages as located and stable systems and of literacies as standardised ways of reading and writing texts. This study contrasts children's digital communicative literacy practices in two homes in Cape Town, South Africa, showing major differences between how suburban middle-class children, on one hand, and urban township children encounter and engage with digital resources at home. Drawing on an understanding of new media as placed resources which operate in specific ways in particular contexts, this study shows these children as material, social and cognitive "sites" where linguistic and sociopolitical norms are engaged with, absorbed and enacted. Rather than democratising resources, this research shows digital media as at least partially complicit in a "widening of the gap" to the extent that the differential uses and availability of resources across social classes produce different imaginings of self, social ambitions and investments, and differing ways with social semiotics. Such differences translate into and contribute to the maintenance of social inequalities in school settings that coincide with language and social class divides.
