I think you all know and use some social networks so i don`t have to tell you much more about the features.
People use social networking sites for social interaction, for finding old friends or for meeting new people with the same interests and so more and more friends- and relationsships are being formed. But social network is not only used for communication with friends, also teachers and students use it as a communication tool. You also can find companys there which make advertising or that you can network with professionals for internship and job opportunities.
About the issues that came up with social networks like for example privacy we can discuss many hours or days. And i think everyone how decide to join some social network should know the problems about privacy!

Do you know the problem? Do you care about it?

I think most of the people haven't thought about it. They don't care, because they don't know something about the consequences. They join the social network and never change the settings or don`t care about the rights they give up for example after uploading pictures. Especially childern don`t know about the disadvantages and danger! ...sad but true...
