title: [At the heart of Internet].
abstract: Internet combines features of both a "coffee shop" and a "very large library". It is different from these two institutions in the innovating approach to information and its communication. The information is obtained by navigators, who recover documents dispersed in the four corners of the World Wide Web. The hypertext links between these documents explain the originality of the Web. They are a permanent invitation to look "somewhere else" to enrich the original site. Electronic messengers facilitate the exchange of information and documents. Room for discussion is available for all in the forums and to a well identified community in the lists of users. Internet is a decentralised and anarchic system. In order not to get lost, the sign posts must be followed. To avoid being a nuisance, there are rules of good conduct. You must not expect too much in order not to be disappointed: absolute security (with the risk of not having access) and perfect adequation of content (because of the risk of the loss of freedom of expression).
