POST1 An analysis of the social media

Before i attend this course i'm not sure about what social media exactly is,what are we able to get from the social media. In my opinion, social media may be just some kind of appications on PC or phone which are used by people to communicate with others and share their thoughts and news.
Now i think it's just too simple to define this course. Social media is not only for entertainment but also for some other official using. By anlyzing the social media we could be able to know what people are thinking about then we can get  important data. By using the data we get from the internet we konw the relationship between the customers and the sellers which is quite crucial for a company to run its business well. This data is for financial using. Also the goverment could know about what the citizens are thinking about and then make some changes to improve people's life.

All in all, it is important to analyze the social media, not just for individuals but also for the entire society.
