In the “Health 2.0” era, digital media has altered how health care is conducted and how patients consume medical information. This article explores the reasons why health-care professionals create their own blogs and how they use blogging as a component of their work. We examine interviews with medical bloggers ( n = 83) featured on “Grand Rounds,” a weekly medical blog forum or “carnival,” to interpret the ways in which blogging is incorporated into their everyday lives. In performing a qualitative thematic analysis, we develop five themes that help capture what blogs mean to these health-care practitioners. The uses of blogs speak to articulating and reestablishing a professional reputation, connecting with patients informally, writing for therapeutic reasons, negotiating institutional constraints, and promoting community and health-care reform.
