Recent years, a ‘storm’ sweeps all over the world which is called ‘Social Network Site’. Social Network Site is a kind of service website through which one can set up his or her Personal Home Page and share interesting news with others. The principle that “Friend of friend’s is my friend” has been accepted by more and more people.
In China, there are several popular Social Network Sites such as Qzone, RenRen and Weibo. According to the latest survey, the amount of weibo users has reached 200 million, and this number is still increaseing at incredible speed. Apparently, Social Network Site plays an important role in people’s life today. In my opinion, two aspects of advantages has contributed to the popularity. Firstly, we stay in touch with our friends in a straightforward way and enlarge the scope of our social intercourse. Moreover, we could search the internet to find the friends that we haven’t seen for ages. Secondarily, the news could spread on the Social Network Site in a more efficient way because of the friendship which means your friends are prone to accept the information, thus giving an opportunity to advertizing companies.
However, everything has two sides, so does Social Network Site.Among all the negative factors, problem of security has caused people’s trepidation. Besides, more and more employees spend much time brownsing these websites. Furthermore, we can’t improve our interpersonal skill in the real life through the activities online. As a result, a group of people insist that disadvantages of Social Network Site overweigh the advantages.
Actually, problems do exist, but we should not refuse to do what we should for fear of running a risk. In order to settle these problems, we could make laws to secure regulation of the websites. In addition, we must strengthen the consciousness of protecting ourselves. I’m sure Social Network Site will serve our life better in the future.
