SNS

Do you know SNS? It stands for Social Networking Service. Even if you don't know, you might know mixi. It's very popular among young people these days, that some people get involved in it too much. The purpose of the SNS is to let people able to communicate with each other and get to know about their friends better. But I do not agree with this. From my experience, I think mixi worsens a relationship from time to time. What do you think about this fact?? I would love to hear your opinion.
