Lately an increasing number of authors concern themselves with the social aspects of electronic networking. Guided by these computer-mediated communications specialists, this article describes and analyzes the emergence of social phenomena on the « net ». Travel in virtual communities or cybersocieties is always accompanied by tension between the real and the virtual. Above all, the text is primary. The omnipresent questions are how a database can be converted into a social space, how rules, conventions and new cultures are born. Finally, how can people's identities be affected by virtual environments. It is by looking at what people do on the networks that the authors - all of whom have different perspectives - attempt to answer these questions.
