Abstract This special issue on ‘Return to Cyberia’ is an attempt to evaluate the contemporary moment of new cultural and social forms influenced by rapidly evolving technologies in their first critical decade. It contains five case studies that highlight the range of transnational experiences - from temporary migrants and refugees to the second generation. The contributors address how and why transnational populations use particular communication technologies and the ways in which these practices are influenced by factors such as generation, history of settlement and dispersal, cultural values, class and access. In addition to addressing a wide variety of study populations, the case studies highlight the variety of available ICTs including email and the Internet, teleconferencing, telephones and mobile phones. Collectively, the articles address issues such as geographic identity and connectivity, different use patterns based on gender and generation, authenticity and representation on the Internet, methodology and the intricacies of interpersonal dynamics across transnational social fields.
