I think this research is important because we are living in social media’s stream. In comScore’s research result, internet users are spending on social network services in every one minute out of five minutes. In Latin America, each person spends about 7.6hours a day on social network services. People can contact with their families and friends easily even in other countries, watching TV without television, and we can see some products’ ads and give feedback immediately to the company. Also, people can play games not lonely, but with friends through social media games. Like this results social media brought lot of changes in our life. This research shows that how much our life is convenient with social media. However, it creates some negative things like addictions to games and social network services, stealing privacy information, exposure to crimes cause of showing personal schedules. I think our life is much more comfortable and rich with social media, but users must aware that we need to protect our privacy information, and safety with less update of personal life details. Also social network service companies need to create and improve programs for protecting their social network service users’ privacy and safety.
