Although the Internet is now two decades old, a second generation of applications (known as web2.0) has experienced exponential growth over the past few years. These sites are characterized by their high level of interactivity, their connectivity and their social network dimension. After a quick overview of the web 2.0' s technical features, we will examine in this article the complex relationship that the law entertains with information and communication technologies whose development happens at a much faster pace than what the justice system is used to. In the second half of the article, we use an incident database we developed in order to examine the criminal and reputational risks associated with the web 2.0. We are especially interested in the exaggerated and distorted claims made in the mainstream media about those risks.
