I co-edited (with Michael Wade) a special issue on Empirical Research on Free/Libre Open Source Software for JAIS, Journal of the Association for Information Systems. The special issue has appeared (2 issues, in fact, with a final paper to come in January). We were able to convince the publisher that they should make these issues open, so they are free to everyone.
I'll be teaching an introductory workshop on social network analysis, 7-9 April 2010, at University of Mysore International School of Information Management. More details can be found on their website: http://www.isim.ac.in/snaworkshop/index.htm
