 Since then BROG has expanded its focus to include research on gender, visual design, audience, and interconnectivity of weblogs.Since 2004, the project has made extensive use of Social Network Analysis methods and network visualizations.The presentation of BROG's research at the 2003 AoIR conference generated controversy among some bloggers who were present at the conference and others who were not about whether people who were "not bloggers" (two of the four original BROG members kept blogs at the time) could legitimately conduct research on blogs.
