Years ago, if a person had some problems in his life, he might go home and write in his diary. Now he
might go onto the Internet and write about them in a blog (博客).
     Differences between a blog and a diary
     Usually, a person thinks of his diary as a book full of secrets. He does not want to share. But in the blog,
anyone can read what he writes.
     Problems with blogging
     The biggest problem with blogging is that anyone can read what you write.
     It is easy to hurt others'feelings in a blog. Because we do not always think about things carefully before
we write about our days. So we have to be very careful about what we write.
      Keeping in touch with friends
     Blogging has both good and bad points of course. People choose to blog because they know that their
friends will read what they write.
     Blogs are a very good way to write about daily life, if people are careful about what they write. However,
I still prefer (更喜欢) writing in my diary!
