SNS Make Us Communicate Easier?

It is a time of SNS (social networking service) . People around me use various kinds of tools for immediate communication . SNS makes it easier for us to communicate with others. I say this is in the situation that it works.
As a person in the young generation of adults in the society, I must say that I really see many inventions of this world. QQ, Renren, Wei Chat are all among them. As I studied in the primary school, there had been already articles talk about the disadvantages of the QQ. QQ was set up as a tool to communicate with stranger at that time. Strangers will find a time to see each other, some of them become good friends , even couples, after talking with each other. The thing is they feel they are special to the past, they can gain a special feeling from the unusual relationship. Therefore, other kinds of the relationships established,and some of them are really bad. These kinds of strange relationship often stopped suddenly and make the victim and the family hurt.
Unlike the adults, when we students use the QQ, at the first time, we were told that "you must never add somebody to the list that you do not know, that is horrible". For a girl in the adolescence, this kind of words have never worked. I started to have more and more strangers in the list. We talk about hometown and our appearance, because we can not see each other at that time. The relationship with the strangers goes like this, until one day a boy in my class talk to me through QQ. He said that he was fond of me and wanted to go out with me at weekends. I knew most of my friends stopped talking with strangers when they met someone in real life. However someone keeps seeking in the sea of net.
QQ is like a friend at that time. If a person feel lonely or they have something do not want to share with all the friendship, he may not first think of finding a stranger to talk on the Internet, but it can be a choice. A friend can be good , can be bad and sometimes, you have to choose between friends and your own life. That is the problem that we tend to be quiet in the crowd . The raising concern for the youth make us to carry out a research about surfing the net healthily. The research we carried out in 2010 shows that there were 33% of the local middle school students used their QQ only to talk with strangers. And 80% of them had an inclination of having an amorous relationship. From my point of view, middle school students should use more time in communicating with their own classmate. When they go to collage, their classmates will not so closed to them any more.
Nowadays we are using too many tools to communicating with others. Sometimes I think of going back to the day that we just have a telephone in the house. for when I really want to know if somebody think of me and send me something, I have to check all the possible ways that he or she can contact with me.
