The Blau Exchange researches the social aspects of the web.
"Blau Exchange is a web-based project that should serve as an intermediary between various professional groups interested in the socially evolving World Wide Web. It is named in honor of Peter Blau, one of the 20th century's most influential sociologists.
My name is Paul DiPerna, and I launched Blau Exchange in July 2006. I recently completed a stint as a social science researcher and administrator at the Brookings Institution, a public policy think tank located in Washington DC. I worked at Brookings for about six years. I've been researching social networking websites and their organizations since June 2004."
