Social digital networking is a facet of living that recognizes no national borders or social boundaries and has become a way of life. This paper investigates the social networking habits of students at Lingnan University and considers how these habits can be channelled for academic purposes by introducing an ePortfolio system into their language enhancement courses. The investigation analyzed the purpose and usage of these social profiles thus forming the basis of the need for academic profiles. After considering the attitudes and motivations of students, this paper reports on the adoption of an ePortfolio platform which best suits the academic needs of students by introducing it into two important language enhancement courses. The paper thus explores students' attitudes towards two forms of digital identities: social and academic. This process has led to arriving at an ePortfolio system that is in sync with the other digitized aspects of students' lives.
