Are Social Networking Sites Good for our Society?

Now, more and more young people love to join social networking that about Facebook，Twice，and Google. They can share everything that are they want about photos, links, and music. I think that is not good for our Society. First, most networking companies have a lot of information that is from user. When a networking company closed down, the information was been sell. So, a lot of person information would be leaked. Second, the social networking company are free because they have a lot of advertising. However, a little advertising is not good for young people. For example some Cigarette advertising puts on web. Third, government join in social networking that is bad for user. more than half internet user love use social networking because it is free. When the government join in the social, they will try to control it. For example, people call the Chinese internet is “Local area network” because they do not want some trouble information. So they control the internet.
