Abstract
Nowadays, who doesn't use Facebook, Twitter, MySpace, Youtube, Linkedin or other kind of social media? Even parents and grand parents use ti nowadays. Social media are omnipresent in our lives. But before going further, let's define what social media is. Social media include forms of electronic communication (as web sites for social networking and microblogging) through which users create online communities to share information, ideas, personal messages, and other content as pictures, videos, links and so on. As for traditional media, they deliver content but don't allow readers, viewers and listeners to participate in the creation or development of the content.
More and more people are attracted by this kind of communication, especially by Facebook, because it is simple, free, and it is a way to keep in touch with family and friends. Furthermore, a lot of firms use them to spread adverts, and to make their own business.
However, do Facebook and social media mean an opportunity or a threat for users?
It is indeed at the beginning of the 21st century that users were beginning to see the appeal of social networking and blogging sites like Friendster, Linkedin, and MySpace. The last one (MySpace), had grown to be the most popular social network in the world. Users could create their own profile, and then post music from artists or videos from others websites.
