Years ago, if a teenager(青少年) had some problems in his life, he might write them in his diary. Now a teenager with the same problems might get on the Internet and write in his blog(博客). In many ways, a diary and a blog are almost the same. So, what makes a blog different from a diary?
The biggest difference is that a blog is much more public(公开的) than a diary. Usually, a teenager likes hiding his diary book and treats it as one full of secrets. Both diaries and blogs tell what happened to the writer that day.
A blog has both good and bad points. The biggest problem is that anyone can read what you write in your blog. If you are not pleased with a friend during school and write something bad about him or her on the Internet, that friend may read your blog and get angry. So we have to be careful of what we write.
A blog has good points, of course. People choose to write in blogs: they know that their friends will read what they write. If you are feeling sad one day and write in your diary, no one will know about it. If you write the same words in your blog, your friends may quickly write back to comfort(安慰) you or give their help. Blogs help people stay in close contact(联系) and let them know what their friends are doing.
