This document summarizes a study on adolescent diary blogs and who their posts are addressing. It defines what makes a blog a diary blog and how they differ from paper diaries. It also defines adolescence and cites studies showing a large percentage of bloggers are adolescents. The document then analyzes diary blogs through the framework of personal narrative performance and Langellier's typology of personal narrative audiences, which include witness, therapist, cultural theorist, narrative analyst, and critic. The rest of the document provides examples of blog posts that fit each audience type and outlines future areas of research.
