The document summarizes research from two studies about online communication and identity formation among teenagers and college students. The first study examines the blogs and websites of three teenagers from different ethnic backgrounds. It finds that these online platforms allow them to express multiple identities beyond national boundaries. The second study uses surveys and interviews to understand how college students use Facebook and how it relates to their racial, ethnic, and gender identities. Key themes that emerged include self-presentation, performance of identity, social connections, and differences in use and perspectives between genders and races.
