Blogs (博客) are the place where young people go to reveal(释放) their souls（灵魂）. Many people enjoy the freedom in blogging. Some, however, find that putting one’s life online can have a price. Some students in America got suspensions (暂停) because on their blogs they posted threatening words to their teachers.
Recent surveys found that nearly one fifth of teens who have access to the Web have their own blogs. And 38% of teens say they read other people’s blogs. By comparison, about a tenth of adults have their own blogs and a quarter say they read other people’s online journals.
With the development of the Internet, more and more people will be engaged in blogging.
In another survey, 79% of teens agreed that people at their age aren’t careful enough when giving out information about themselves online. Besides, careless blogging can also affect blog viewers. When you are angry or frustrated, your blog is the first place you turn to. The words you post then may not be rational which you may regret(后悔) later. To reduce the negative effect, change the permission setting and make such posts “private” so that only you can read them.
As long as you are careful with what you post, blogging is a great means of staying in touch with friends and displaying one’s creative works.
