At that time, Zuckerberg was helped by Dustin Moskovitz and Chris Hughes for site promotion and Facebook expanded all ‘ Stanford University , at Columbia University and at ‘ Yale University . This expansion continued in April 2004 when it extended to the rest of the Ivy League , at MIT , the Boston University and Boston College .

The site is free to users and derives revenue from advertising , including banner . Many analysts argue instead that the monetary income of Facebook are not as high compared to the potential of a social network service , averaging about $ 230 million in 2009. In fact only in 2009, after 5 years from its inception, the portal is able to close the first budget surplus. Revenues from advertising sales fail to cover only part of the fixed costs of running the site (storage, servers, etc..) So as to require the contribution of members (including the 1, 6% of Microsoft). [ 13]
Users create profiles that often contain photos and lists of personal interests, exchange private messages or public and are part of groups of friends. The vision of the detailed data of the profile is restricted to users at your friends or accepted by the user. According to TechCrunch , “about 85% of college students have a profile on the site. Of those who enrolled, 60% accessed the site daily. About 85% at least once a week, and 93% at least once a month. ” According to Chris Hughes, spokesman for Facebook, “People spend about 19 ​​minutes a day on Facebook”. [14] The members of Facebook can choose to join one or more networks, organized by city, workplace, school and religion . Facebook is similar to MySpace , but a significant difference between the two platforms is the level of personal customization of the page. While MySpace allows users to decorate the profiles using the ‘ HTML and CSS , on Facebook you can only enter text.

Facebook includes some services that are available on the mobile device, such as the ability to upload content, receive and reply to messages, send and receive poke , write on the bulletin board users or just the ability to browse the network .
Another feature of the Facebook profile is the “mini-feed” shows that their actions and those of friends, in a public timeline not unlike that of Twitter . The difference is that with Twitter updates you decide what will be shared directly, while with the Facebook newsfeed every action is monitored and transmitted. However, only users added to your list of friends will be aware of such information.
Facebook makes use of AJAX in your web pages.

Facebook Connect
In autumn 2008, Facebook has made ​​available a system API used to integrate external sites with the site. Using Connect can connect their Facebook account with the one used to insert comments or articles on an external site, such as a blog. In practice, you can bring your own identity outside of Facebook, using it on sites that support Facebook Connect. From a technical standpoint Connect is made ​​possible by a particular library Javascript issued from Facebook and from a language extension of XHTML called FBML , which allows developers to add dynamic elements to be generated on the Facebook pages of a site.
Facebook Beacon
Beacon was a part of the publicity of Facebook that was sending data to sites outside of Facebook, ostensibly to enable targeted advertisements and allow users to share activities with their friends. Some activities on the partner sites were published on the News Feed user. Beacon was launched on 6 November 2007 with 44 partner sites. The service, a rather controversial, became the object of a class action and was suspended in September 2009. [20]
Facebook Markup Language
FBML is a pseudo-language, HTML style, which lets you place content into the Facebook applications such as buttons, forms, multimedia, and much more. The language FBML is then parsed by the same Facebook that “translates” his special tags in HTML and styles needed. [21]
Privacy and disputes

Reason : This section is a collection of facts becoming disconnected from each other, mostly Italian with a view only. It would be more useful to confine the analysis of privacy law and its evolution over time.
Join the discussion and / or correct the entry.
Several problems [22] have arisen regarding the use of Facebook as a means of control and as a mine of data.
Initially there was no granular control of who-can-see-what. From 31 May 2010 you can apply privacy settings to the individual post or individual comments [23] . She was also extended the list of “levels”, adding a custom level. The levels are:
I (only for photos)
Friends
Friends of friends
Friends and Networks
All
Custom
These levels can be set independently for each “category” of profile information on data elements (comments, posts, etc..) Or on personal data (such as “Birthday”, “Political and religious”, “Education and Work “, etc..). [24] [25]
By operating on the profile settings so you can limit the spread of personal data. In particular in the menu settings is available the entry on privacy settings , from which you can act on the categories of data including: profile, search, news and bulletin board. Of course, these settings do not restrict access to those data where site managers assign administrative privileges, for reasons of order and legal.
Initially, Facebook only allowed to disable the account so that was no longer visible on the site and in search engines. As of 28 February 2008 the user also has an option available that permanently delete their data from the server site.
However you think of pictures and videos taken on the bulletin board of other users, or photos posted by third parties in which a user is tagged, the edge behind his consent. Once tagged in a photo, not just a text or video images were copied to the profile of other users, this material can not be eliminated (unless required), even when the person decides to delete his profile. The cancellation is limited to the personal profile, but not everything was copied from a third party or shared with others.
Furthermore, the content posted by members (such as photographs, video and comments) are the property of the site . Rare case in law, the site says the owner, but not responsible for the content, and, like many other content providers , refuses to censor or limit the visibility of content and groups, rejects the criticism concerning defamatory, which incite to crime penalties, and demands for damages that can be moved in such circumstances.
According to the Italian code of personal data protection, ownership of the content does not extinguish the individual rights of those concerned. If these are the authors of content, transfer of title to the site at the time of publication, again, extinguished the rights relating to copyright, not subjective ones. You have the right to obtain information about the processing of personal data of third parties that have entered into possession, to prohibit the publication, and to finalize its removal from the site, you must destroy all copies of personal data in its possession, and disclose the cancellation request to third parties who have acquired these data through it. [26]
The international attention and criticism of various actors, both national organizations that have led to a May 2010 review of the management of privacy that slightly increases the granularity but with certainty the accuracy and clarity with which the user with the use and vision of a single grid will access the setting of the various aspects of the privacy of your profile. [ unclear ] [27]
Two students from the Massachusetts Institute of Technology managed to download over 70,000 Facebook profiles using a shell script automatically. In May of 2008 a program of the BBC , Click , showed that it was possible to steal the personal information of a user and his friends with malicious applications. [28]
Facebook is also subject to the phenomenon of creating fake profiles of famous people. [29] [30]
Numerous cases in Italy of a breach of privacy for publishing photos of “inconvenient”. On May 14, 2009 are discovered photos of patients intubated visible on the site, and the nurse who had published had not noticed that they were within reach of all. [31]
At the end of October 2009 on Facebook, appeared injuries and insults by a panel discussion titled “Kill Berlusconi”. Following the media emphasized the minister Maroni has promised to denounce those who spoke and prosecution. [32] [33]
On the site you’ve created several groups who have previously chanted to Salvatore Riina and the massacre of Srebrenica . [34] [35]
In May 2010 the Pakistan and Bangladesh have decided the blackout of Facebook and Youtube to prevent the spread of caricatures of the Prophet Muhammad . [36]
In September 2010, on Facebook, after a study carried out in laboratory safety AVG Technologies , were found about 11,000 infected pages that endanger users, mostly exposed to identity theft. [37]
Recently, Facebook has opted in facial recognition of picture contributed by users, causing some controversy for privacy. [38]
Analysis of the social dynamics of Facebook

In an article posted on his personal blog, Facebook hired by the sociologist, Cameron Marlow , [39] has made ​​public the details of a study [40] conducted by the Facebook Data Team on the social dynamics of subscribers. The purpose of this study was to determine if Facebook increases the size of an individual’s personal network. [41] To answer this question, the study has created a qualitative distinction of Facebook friends into three subgroups internal to a larger group.
The group generally refers to “all friends”, [40] or to the list of people that a Facebook user as such. According to Marlow, the word “friends” in this context seems somewhat ‘ambiguous. The curiosity of users who ask him to assess whether they have enough friends on Facebook or if they have a few, the sociologist says that the language used might lead to committing an error. Those who, in the language in use are considered as friends, might be simply an individual who has met at some point in his life. Regarding the number of the social network, Facebook’s official data [42] reproduced by Marlow speak of 120 friends for the average user. The same, however, Marlow says that this figure may be significant to estimate the size of a person’s social network. First, because the site is still young enough and the number of subscribers is still relatively low. This means that not all people known to be a registered user on Facebook can be recorded at this site and would undermine the ability of the individual to build his social network that matches that could build by other means. In this regard, Marlow cites another tool for estimating the size of an individual’s social network: was quoted by the writer Malcolm Gladwell in his book The Tipping Point and refers to the studies of Peter Killworth and his collaborators. [ 43] These researchers used a list of names and surnames taken from a telephone directory and estimated the size of an individual’s social network on its ability to recognize the names on the list as people encountered. This method led to an estimate of the social network developed during the life ranging from 300 to 3000 people.
The data for the three subgroups were processed for 30 days by monitoring the activity of a random sample of users. [40] monitored the activities relate to the types of communication that Facebook provides users to keep in touch with members of his personal social network.
The first subgroup refers to reports maintained in a passive manner with the use of tools like the News Feed or RSS readers. Search within these technological tools in the management of the report because, according to Marlow, the consumption of content accessible by these means can be transformed into other forms of communication. [44] For example, if the former high school classmate of public Facebook a photo of her new puppy, you can click on the news, check out many more photos and find out among other things that is engaged, or had a child, and this could lead to contact with her. In measuring the size of this subgroup, the researchers were limited to record the number of friends a user has visited with some repetition, more than twice during the thirty days of searching, clicking on the News Feed or display the profile .
The second subgroup is built around the use of technologies of communication “one way” (one-way communication) as are the comments to photos, status messages or post on the wall of a friend.
The third subgroup is built around the use of technologies based on mutual communication , or an active exchange of information between two people chatting or exchanging messages via email.
The general trend of users, [40] [45] considered the sexual distinction, shows that people on Facebook using the various forms of communication expressing a commitment differently depending on the type of technology. Compared to their buddy list, users are kept informed (or clicking on the News Feed on RSS, or by visiting the profile) with a less conspicuous number of friends. The number drops even further when it comes to using technology to “one way” (comments on photos or status messages, or post on the wall), to be further reduced with the use of two-way communication (chat and exchange e- mail).
The data based on the kind of sex show the user a different propensity of the two sexes [40] [46] [47] in the use of these technologies: the women were generally more active than men in their use.
When users, male and female, have a list of 500 friends, women on average will keep each other informed via RSS News Feed and profile views of 47 members of their social network, men, on the other hand, use this technology to keep you on average of 39 of their 500 friends on Facebook. The women use communication to “one way” with an average of 26 of their friends, with 17 men. The mutual use of technology (chat and exchange messages via e-mail) is even more limited: compared to 500 women s’intrattengono friends through this type of communication with 16 friends, with 10 men.
Users with a list of 150 friends build around themselves a subset of relationships through Facebook and women is on average 22 out of 150 for relations maintained, 19 for men, women send communications to “one way” 11 to 150 of their friends, the men at 7, 7 out of 150 are on average mutual communications with friends for women, 5 for men.
