Many students are using and enjoying Social Network Services (SNS) including Facebook, Twitter or blogs. They just click buttons such as “like” on Facebook, implying that they agree with various posts. There are people who leave comments on posts to indicate other kinds of suggestions or opinions. Sometimes other people just click the button again to contradict the first comment. Do they really express their own opinion? Why don?t they post on their own SNS account rather than expressing their thoughts by clicking the button?

Recently, when I saw a post on Facebook regarding whether Park Chul, a former President of HUFS, should be appointed as an honorary professor or not, someone replied by posting an article in opposition to the appointment. At the same time, she also supported an argument in favor of the appointment. What is the meaning of her actions? I was confused about what she thought. Another example is a post mocking someone for gaining popularity online through even using a hidden camera. Then many people, more than seemed reasonable to me, liked the post because they do not care about the object of ridicule.

I think public opinion can be created without much effort through massive peer pressure. This means that many people are clicking “like” based on the number of “likes,” which lacks consideration. The more “likes” something has, the more influence it has. Thus, people find it easy to support the post with a large number of “likes.” However, expressing our opinions is very important not only for students but for all people. Because hundreds and thousands of opinions can change the world, we must express our own thoughts exactly.
