This document discusses computer-mediated communication (CMC) and diffusion theories. It addresses how CMC has developed from bulletin board systems into the modern internet and social media. CMC plays a central role in online social dynamics and influences how people present their identities online. Diffusion theory examines how new technologies and ideas spread through populations in a process involving different categories of adopters from innovators to laggards. Social media platforms allow for networking and sharing information between connections in ways that can both connect people and potentially distance them from direct interactions.
