The widespread adoption of CMC in the context of education and research has given rise to a new sub-culture in which patterns of communication, expectations of social communication exchanges, and language formality have changed. In this paper, we describe a diary-log study of Computer-Mediated Communication (CMC) usage amongst youth in Arabic-Speaking populations. This qualitative study examined diary logs of CMC patterns of 61 youth participants, ages ranging between 14 to 24 years.
