Julia Habermann: Analysis of the usage and value of weblogs as a source of business news and information
German information science student Julia Habermann recently completed a thesis with the above title. She has given Jack Vinson (of Knowledge Jolt with Jack) permission to post an overview report and the data from the survey. She did a nice job. It looks like her n=415, but the respondants seem to be mostly librarians. A good next step would be to survey middle managers or upper managers in for-profits. BTW- the top blog is ResourceShelf by a landslide so the survey folks have good taste, too.
