Nora Barnes has released the results of research into blogging from the Center for Marketing Research at UMass Dartmouth, where she is the Director and a Professor. This is a welcome addition to the sparse collection of research that has been conducted to date. The published report is free and is available (as a 1.3mb PDF) here, or from the Center, where there is also a link to a podcast of an interview with Nora, and links to comments from others on the study.
