Researchers:

• http://people.oii.ox.ac.uk/hogan/ – Bernie’s research interests lie at the intersection of social networks
  and media convergence. That is, what medium do people use with their ties, and when? With new media, individuals simultaneously have more convenience but also more complexity, expenses and social pressure to adopt. Some individuals thrive in this new media ecology, while others feel it has isolated them. Within this framework, Bernie examines the eroding home-work boundary, the digital self, and the shift from public spaces to cyberpublics.
• http://toreopsahl.com/ – Tore explores and throw out in the open some of the ideas about social network analysis that has. Many of his ideas stem from my interest in weighted networks and his belief that the weights are an enormous source of data. However, many social network measures require that the weights are discarded. In so doing, the richness of the data is considerably reduced. In turn, this limits the analysis.
• http://www.drewconway.com – Drew studies international relations, conflict and terrorism using the tools of mathematics, statistics and computer science in an attempt to gain a deeper understanding of these phenomena.  His academic curiosity is informed by his years as an analyst in the U.S. intelligence and defense communities.As part of his research he maintain a blog called Zero Intelligence Agents, which asks the question, “How can the social sciences, mathematics and computer science combine to affect national security policy?”
• http://www.orgnet.com/ – Valdis Krebs is the Founder, and Chief Scientist, at orgnet.com. Valdis is a management consultant, researcher, trainer, author, and the developer of InFlow software for social and organizational network. Orgnet provides software, training, consulting, and research for the application of network analysis in a wide variety of domains. Make sure to check his blog: Network Weaving 
• http://www.steveborgatti.com/ – Steve Borgatti is a Professor and Endowed Chair at the University of Kentucky in the Management Dept. of the Gatton College of Business and Economics. His research is focused on social networks.  You have been probably using UCINET, so he is the man behind it. Make sure to check his great teaching page. It is full of great material : http://www.steveborgatti.com/teaching.htm
• http://stat.gamma.rug.nl/snijders/ – Tom A.B. Snijders is Professor of Statistics in the Social Sciences at the University of Oxford, and Professor of Methodology and Statistics in the Faculty of Behavioral and Social Sciences at the University of Groningen . He is the face behind SIENNA a great software for the statistical analysis of network data, with the focus on social networks.
• http://cs.stanford.edu/people/jure/ – Jure is an  assistant professor of Computer Science at Stanford University.His  research focuses on mining and modeling large social and information networks, their evolution, and diffusion of information and influence over them. Problems I investigate are motivated by large scale data, the Web and on-line media. Make sure to see one of videos the many talks he gives, they are fun to watch and I learned a lot from them . He also provides a great source of various network data, in case you are looking for some: http://snap.stanford.edu/
  
• http://www.ethanzuckerman.com/blog/– Ethan was a co-founder of Tripod.com, a web hosting enterprise, and later founder of Geekcorps. He currently serves as a fellow at the Berkman Center for Internet and Society. His work at the Berkman Center has included research into global media attention.
• http://www.danah.org/ – Danah is a Social Media Researcher at Microsoft Research New England and a Fellow at Harvard University’s Berkman Center for Internet and Society. She recently completed my PhD at the School of Information (iSchool) at the University of California (Berkeley). Her research examines social media, youth practices, tensions between public and private, social network sites, and other intersections between technology and society.
• http://beamtenherrschaft.blogspot.com/ – Ralf has a diploma degree and a doctoral degree both in computer science from RWTH Aachen University. Currently, he leads a research group at the information systems chair, RWTH Aachen University. In 2001, he was a visiting fellow at the MIT Entrepreneurship Center of MIT Sloan School of Management.

Institutes & Organizations:

• http://www.webecologyproject.org/ – The Web Ecology Project is an interdisciplinary research group based in Boston, Massachusetts focusing on using large scale data mining to analyze the system-wide
  flows of culture and community onine. In addition to the task of understanding culture on the web through quantitative research and rigorous experimentation, they are attempting to build a science around
  community management and social media. To that end, they are building tools and conducting research that enable planners to launch data-driven campaigns backed by network science.
• http://www.casos.cs.cmu.edu/index.html – CASOS is a university wide center drawing on a group of world class faculty, students and research and administrative staff in multiple departments at Carnegie Mellon. CASOS fosters multi-disciplinary research in which students and faculty work with students and faculty in other universities as well as scientists and practitioners in industry and government.Make sure to check out ORA a very fine tool for network analysis.
• http://www.insna.org/ – INSNA is the professional association for researchers interested in social network analysis. You will find all the people and a lot of helpful material there. Make sure to check out the Sunbelt conference http://www.insna.org/sunbelt/current.html. I had the pleasure to present some of my work there.
• http://cyber.law.harvard.edu/ – The Berkman Center’s mission is to explore and understand cyberspace; to study its development, dynamics, norms, and standards; and to assess the need or lack thereof for laws and sanctions. They are a research center, premised on the observation that what they seek to learn is not already recorded. Their method is to build out into cyberspace, record data as we go, self-study, and share. Our mode is entrepreneurial nonprofit.
• http://www.oii.ox.ac.uk/ – The Oxford Internet Institute was founded as a department of the University of Oxford in 2001, as an academic centre for the study of the societal implications of the Internet. The current home in a building owned by Balliol College was formally opened in July 2003.
