NeRDS (the New Research on Digital Societies) group was established in 2013 at Kozminski University in Warsaw (Poland). Our aim is to study digital societies by the means of virtual ethnography, anthropology of the Internet, digital sociology, but also network analysis and other quantitative methods. Our projects so far include studies of open collaboration communities (such as Wikipedia), Couchsurfing, the Second Life, piracy, transhumanism, as well as virtual communities of museums.
