Social media??

Social media is a cyber place where people can meet and discuss. It is usually deeply connected with the Internet. Most types of it contain network systems. Facebook is one of the most popular social media and things like "naver blog" or "blogspot" are also types of social media. I'm not sure but I guess MSN is also a social media. I think its strength is that it is a two-way communication. When a person writes a controversial idea, it can gain strength or lose strength immediately. People read what others think and comment on them freely. Actually, this strength can also be a weakness at the same time. Being free is dangerous. We do not know how much people can criticize on some issues. This is quite scary.
