Years ago，if a teenager had some problems in his life，he might write them in his diary. Now he might get on the Internet and write them in his blog(博客). In many ways，a diary and a blog are almost the same. Then，what makes a blog different from a diary?
The biggest difference is that a blog is much more public than a diary. Anyone can read what you write in your blog. Usually，a teenager likes hiding his diary book and treats it as secret. If you are not satisfied with a friend and write something bad about him in your diary，he will never know it. However，if you do this 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 feel 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 you and offer their help. Blogs help people know what their friends are doing.
Though it's a good way to write blogs about everyday life，I still prefer my old diary.
