This is a vast topic, i must explain serveral things to do understand my thinking.
First , does Social network is an achievement ?
Yes, absolutly so i can’t say that is a bad things.
But there are different points of view, it’s a fact the social networks are permitted that people can communicate better than before, can have access about information quickly.
I could write a lot of good points about that, and all people know that.
Nevertheless all the things aren’t good, i’m thinking about the sad news, for example the childrens who have a lot of problems on the network, sometimes they can give themselves the death…
Because when a publication is written on the web all people can be informing about that, and the news go quickly !
Some lifes have been broken because of stories of childrens.
Some people show their sexual life, or personal informations.
Currently, people can do and say all that they want, but in my opinion it’s too much, i want that all people can say all that they want but our identity must be able to control…
In short the social network is a very good evolution but it must have a lot of control.
