Social networks are websites that allow you to put people in touch and give birth relation ni. Allow you to communicate and share their lives with others who live anywhere in the world. To become part of a social network community is necessary to make a registration, filling in the data request form for the new user profile. through the creating a personal profile who signs up can tell something about themselves; publish im- Magini, links, music and videos; participate in thematic groups and their discussions; interact with other users in several ways. E 'can search for people to certain criteria such as age, sex, place of residence, common interests. Social networks are recognized as virtual squares that expand our ability to communicate, even in the political and social sphere, turning us into active agents of campaigns in favor of what we believe. The social network has completely opened and modified the frontiers of digital communication: It integrates into a single "container" various services: the user's profile, blogs, messaging, download music, photo gallery, the community In social networks, is also enhanced a key feature of Web 2.0, that is, participation, the active interest of the members to find friends and cultivate relationships. The Community is made up of a group of users that aggregates based on common interests, to exchange information, seek confrontation, and profiled by activating various modes of in- internal interaction to the group that is formed and that can grow and develop in turn new community more specific. The Community concept in the user develops a sense of identity fication and belonging to a group that has connotations and special skills, which They differ from other groups and determine the identity. Users select the mode communication and socialization that better adhere to the needs of interaction of Community and create strategies to implement the exchange of content and knowledge. Belonging to a group that has self-selected means gaining access to the cultural background, social and emotional of members who belong to it. The use of social networks has seen exponential growth in recent years and involves a increasing number of population. According to the 43 th annual report of Censis (social studies Investment Centre), published earlier this year, are 19.8 million Italians who are familiar with at least one of many existing social networks. Knowledge of Facebook and YouTube is highest among young people of 14-29 years (90.3% and 89.2% respectively), is high among adults (64.2% and 64%) and falls considerably mind only among the elderly (24.6% and 22.9%), among which is the use to be virtually zero (around 1.5%). More than half of young people, however, are using Facebook (56.8%) and more of two thirds YouTube (67.8%), and is not negligible the use YouTube also among adults (23.5%). Even research conducted by the University Cattolica del Sacro Cuore in Milan has confirmed mato l 'importance of social networking sites among boys. "This is not a central, as we shall see, only the user (that is, in terms of 'quantity' of minutes spent or quality, RIS chest involvement and depth in the use of such services), but first and foremost it is a centrality of values. When we are talking about the centrality of the social net work is referred not only to the ability who have these services to communicate, phrasing jars, fit with extreme force in time of young people daily, but it refers also which in a central position that makes sense to the kids these services more and more 'essential'. indis- thinkable as related to a at the same geneity in some cases accelerating and complex, which needs tools that simplify and stabilize relationships and time. But, conversely, essential because in Gra- tools do to increase the multiplicity of reality and opportunities for socializing. "2 There is already talk of the era of Web 2.0 as a now nearing completion period, which is yielding up to the Real Time Web 3, the web of real-time communications, which it represents a new form of communication and to be online: seek and disseminate information on The Internet in the same moment in which they are produced. With this phenomenon emerges the centrality of people in social networks: are the friends we choose the first filtration system of the complexity and heterogeneous suitability of the information online, they will select interesting and valuable content. The new technologies from this point of view they bring into contact with dimensions very Human: often something interests us because it interesting to people close to us.


The number of social networking on the web is constantly growing: there are all kinds and so may be general or focused on a particular topic (music, work, current events, etc.). It 's impossible to take them into consideration all: it will give an overview of the most "popular" and more used by young people.

  • Facebook

Facebook was founded February 4, 2004 by Mark Zuckerberg, then a nineteen-year student at Harvard University. The name of the site refers to yearbooks (called, precisely, "Facebook") with photos of every single member that some public colleges cano beginning of the academic year and distribute to new students and the faculty staff as a means to get to know people on campus. Facebook's initial purpose was to maintain contact between students of universities and high schools around the world, but over time it has expanded and today has become a social network that embraces across all web users. According to data from the same site, at the end of 2009 the number of active users has reached 300 millions around the world.

  • MySpace

  • Twitter

Twitter was created in March 2006 by Obvious Corporation of San Francisco. It's a service that lets you keep in touch with people through the exchange of quick, frequent answers to the question: What is new? You can share and discover what's ac- falling now, anywhere in the world. The set of message status published on Twitter by cost-users therefore constitutes an enormous amount of material, in many cases also a certain quality

  • LinkedIn

  • Habbo

  • Netlog

    Netlog is a Belgian social networking site that It is aimed in particular at the European youth. Has a location technology that It ensures that all content is personally izzati depending on the profile of each member. This allows each user of power carried tuare customized searches and obtain a complete overview of the community, by ensuring that only the profiles of those are shown members from a particular region or who have other characteristics. In addition you can also put photos and screaming "in the spotlight": this is a way to appear on the front page and then be seen by other Netlog users


From a Microsoft research conducted in 11 European countries, including Italy, on 14 thousand users, presented on the occasion of Safer Internet Day 2010, the European Day for Safety in Network shows that young people and parents do not have sufficient awareness of the dangers They meet on the Internet, or rather both are overconfident of their knowledge to avoid really the pitfalls of the Web. According to the survey 79% of European teenagers die now at least has its own page on a social networks and 43% believe it is fully safe to post and share personal information through social media. To the point also enter data online and references particularly sensitive: in Italy, for example, 26% of boys are sharing your home address, 56% indicates the name of their school, 76% are exchanged photos and videos of friends and even 59% the e-mail address or instant messaging. Evidently even just one of these information shared without attention on the Web, can allow potential attackers to open a dangerous front contact. That's why almost two-thirds of European teenagers (63%) were contacted by strangers online, a percentage that rises to 73% in Italy, highest among countries. Not only that: more than 46% of the boys often, driven by curiosity, responding to non-fiat your place. Despite these findings, 59% of parents It declares peaceful navigation in the pro- Network pri guys, convinced that they know to take all precautions to protect and share responsibly mind the information online. So much so that as much as 40% of Italian parents do not control the movements on- line or posts published. Percentage increases when viewed through of the youngest answers: 66% of European teens, in fact, your parents are not nothing to limit or control their use of Inter- net. The same applies to 55% of Italian children, while only 1 in 10 has a parental control system installed on your computer (12%) or using the Internet in the living room instead of in their own room read (15%). 4 The survey on the use of social networking systems 5 conducted by ANSSAIF (National Association of Security Specialists in Companies Financial Intermediation) confirms this trend: more than 55% of respondents do not believe at all concerned of risks associated with the use of social networks, or believes that can happen only to others. And the higher percentage of "not worried" it is in the age group 18-30 years. But there are risks, especially if it makes the Web in general and social networks in particular a little careful and conscious use. A first fundamental problem that can not emerge from a careful use of networks reports on the Internet concerning the choice of personal information to share. Social networks are tools that give the impression of a personal space, or PIC- community cola. But this is a false sense of intimacy that may push users to exhibit too his private life, to reveal very personal information, causing "carried side defects ", even after many years, that should not be underestimated. 6 When you are entering personal information on a social network if it loses control. the data They can be used, processed, disseminated even after many years. Once loaded a photograph, a video, an audio file, you can copy it for anyone on your computer and then, in turn, spread it. For this reason, even if you delete your copy of the file, you can that there are other copies. In addition, too precise personal information made visible in the user's profile can ES- evenings used by potential attackers to locate potential unwitting victims. Another danger spread within the networks of online relationships are the fake profiles, ie per- persons who pretend to be other (declare age, gender, identity different from reality). It 'important so many that you always have the certainty of knowing who we are by relating. Another downside of social networks is the fact that the bad guys have increasing possibility of orchestrating the fraud against the users who take risks frequent viruses that infect computers, causing damage not indifferent, as the violation passwords.

Social networks are also fertile ground for cyberbullies who shoot and move to Network embarrassing photographs, or targeting a user, al lontanandolo from discussions with offensive words, creating sometimes tragic situations. The Network is a powerful amplifier of the information, enabling you to communicate quickly and widespread: an advantage that can turn into problems, when the content is spread harmful


Arrived at this point it is inevitable "on one side wondering what are the underlying reasons that are decreeing the centrality of social networks between consumption and youth imaginary, the other if that happened it should be alarmed or not. Let's step back a little: the cultivation of social relationships on the Internet is not a Novelty 2.0. Internet is populated by decades of social spaces: electronic bulletin boards, chat, forum. What changes with social networks is the 'intensity of these relationships that become less volatile, more established and are closer to off-line relationships. Social networks become ie tools to manage very effectively sociability and its role in the amino Network cizie, knowledge and potential members. Social networks that become a 'network of possibilities': the ability to contact everyone and not lose anyone. A further point concerns the role of the family: several interviewees have recommended counted to have in their contact their family. It is in the highest part of the family 'enlarged': cousins peers or distant relatives (left in the country of origin or in some cases residents abroad). With the latter in particular, it is woven aimed at maintaining relations Contact, who is not 'lose' the link with the extended family network. "There is also to regarded as the most of the time "the boys are more intelligent and moderate use of these instruments than some media representations want to pass often critical to social networks they suffer from a part of a covert conservatism and Luddites, the other of some injury by adults against a world that still understand in part. The characteristic of social networks being accelerators and organizers of relationships and sociability must therefore not frighten, if, as is the case for most of our subjects, such relationships and sociability have the ability to get rich of emotions and meanings pro- funds. "8 Even social networks, so, if well used, are useful: they provide extraordinary opportunities of reality and especially deepening allow analysis and to communicate, get in relationship with others and not always only superficially. There are no real strategies, but to common sense: how it gives the rules of behavior in real life, even in the virtual world must do so. A conscious use and attentive to these new communication tools averts most of the risks and you can just enjoy the beauty of the Internet
