Social network are community on the Internet. They permit to create a profil and to meet people. Sometimes they become virtual friends, that means that you speak with them like with real friends, but only online.
For example, MySpace is the most important social network in the world : it has more next to 1 millions of subscribers. In France, skyblog is a social network too.
Personally, I use Réseau Campus, which is a student network, and Viaduc, a professionnal network.
In the futur, these social network will increase with Internet, because Intrenet generations meet easily people on the Internet than in reality. From marketing point of vue, it’s very interesting because they gather people around commons interest, for example photography, or music… They represent targets for advertise.
