　　On the Popularity of Microblog
　　With the improvement of microblog services and the influence of some “star microbloggers”, most of whom are celebrities, microblog is becoming an important and convenient way for people to express their opinions and communicate with others. Now, more and more people start to use microblog services provided by different websites.
　　However, microblog might give rise to some problems as well. Some microbloggers may become so dependent on microblogs that they would rather express their thoughts and feelings by writing them down in the microblog than communicate with family members or friends. Day by day, microblogs tend to draw them away from their real life. What’s worse, lack of face-to-face communication with others might isolate microbloggers from the society, which would do harm to their mental health.
　　In my view, microblog is a good platform for people to share their personal experiences and communicate with others. But microbloggers should also have a rational attitude toward it and avoid spending too much time on it. After all, sitting in front of the cold screen for a long period of time does no good to their health.
