Blogging Together: An Examination of Group Blogs
This paper presents the first examination of the growing phe- nomenon of multi-author, or group blogs. Using a large col- lection of blog posts gathered over an eight month period, we conducted some quantitative assessments. Multi-author blogs were found to differ significantly from single-and-two au- thor blogs on several quality metrics, including having longer posts on average and being ranked higher according to an in- link metric. Visualization of patterns of posting revealed that individual authors often dominate the posts in multi-author blogs, and that in some cases tags are shared, but usually not extensively.
