　　The Popularity of Microblog

　　In recent years, microblog has become part of our life. People use it to reveal their inner voice, or collect and share thoughts and things they find interesting. Statistics show that over half a billion people are using it.

　　The benefits that microblog has brought us are self-evident. For example, it enables people to convey their emotions and thoughts more instantly and conveniently. It thus also provides a chance for people to release their inner stress. Besides, it offers a platform for relatives and friends to keep in touch at any time.

　　However, microblog can also be potentially dangerous if not properly used. First, being addicted to it is nothing but a waste of time. It may also give away people's privacy or other important information. What's worse, being susceptible to others' ideas easily, people may lose the ability of thinking independently.

　　All in all, mieroblog provides us comfort and also inevitably some concerns. We should be careful while using it.
