This book has become a classic and mandatory consultation text for all the people interested in a very new social phenomenon: the birth and development of so-called virtual communities.
The new communications technologies offer us the possibility to communicate from many to many and this capacity has allowed the creation of groups, associations and families. The virtual communities are the term used to refer to these social groups formed by the mediation of computers and "arise from the Net when a sufficient number of people carry out public discussions for a long time, with enough human feelings to form networks of personal relationships in the cyber space". The members of these communities do practically everything we can do in 'real life' without body, but: discuss, make friends and lose them, flirt and fall in love, play, chat and waste time, do business, give moral and psychological support, exchange ideas and information, etc. Some people spend many hours a day, others use a much more moderate use.
