That is an overview of today's communication. Today one of the most important thing of communication are social networks. Since 1980 social networks become more and more important for our society and the number of interested persons is still increasing.
It is so interesting for people, because anyone can chat or skype with any in the world. It started with simple chat rooms and now we have big blogs and and websites which enables people to share pictures, videos and more. For example in some Networks you can share places where you have been, things that you have done, photos that you have shot, videos or persons that you like, ect. People are able to share their whole lifes. That is an important reason why social networks are so dangerous. Other people can spy you out if you are not careful enough. Or they can post compromising things of you, if they wish to hurt you harm. That is why people should think about, what they share. An other disadvantage of social networks is that you can create a fake account and deceive people. That makes it a lot easier for stalker to spy you out, or for bad guy who will hurt you. Therefore the users should think about which person they trust in social networks. In addition, more and more people are moving into this virtual communication instead of meeting with others and talk.
As comfortable as social networks are, they have some really huge drawbacks.
