Dr. Nora Ganim Barnes at the Center for Marketing Research at the University of Massachusetts Dartmouth surveyed 74 top bloggers about their experiences. The 60-page paper (PDF) is a tome of wonderful advice for starting and running a blog. After a commentary about the results, explaining the major themes in the responses, the raw data of the 22 questions in the survey are presented. It's really a good read.
