social networks

1.1.Definition

A social networking site is an online place where a user can create a profile and build a personal network that connects him or her to other users. Since the creation of the first instant messaging programs, the first social networking sites were starting to become popular between university students. Nowadays, these sites have become a daily gadget and an entertainment and social tool for all types of users: workers and students of all ages.

1.2.History

The first social-network site was created in 1997 and was called SixDegrees. It allowed users to create a profile, list their friends, surf their friends’ profile and share information with them. Ever since, an endless list of social sites were born: AsianAvenue, BlackPlanet, MiGente, etc. Nowadays, many of these websites have disappeared, but instead we can find new sites which have replaced them and are popular between the users. The most popular sites of 2009 are: Myspace, Facebook and Twitter.

1.3. Standard features

According to the definition, the basic feature of a social-network site is the ability to create a profile. Inside this profile, some of the operations which can be made are:

create a blog
upload content: photos and videos from Youtube
share this content
post comments and messages to other friends
create events
collaborate with other friends
have a list of favourite friends

Recently, in some sites like Facebook or Tuenti, there has been included an option which is online chat.

With all these properties, each user can make their own profile unique, showing its interests and concerns.

1.4. Social impact

These sites are aimed at people of all ages. Nevertheless, social-network sites are mainly used by people between 12 and 18 years old, whose addiction to these sites is a fact nowadays. This abuse is due to the endless applications of these sites, which are sharply dicreasing the need of face-to-face communications. The advantages and comfort of these sites make it easier, especially for those who have more difficulties at socializing.

1.5.Privacy

The privacy on the Internet is an important issue and specially in these sites, where uploading pictures and personal information could be a threat. However, large services, such as Netlog or Myspace, work with law enforcement to try to prevent such incidents. Some information altered or removed by the user may be retained or passed to 3rd parties.
