Years ago, if a teenager had some problems in her life, she might go home and write in her diary. Now, a teenager with problems might go onto the Internet and write about his problems in a blog. In many ways a diary and a blog are very . So, what makes blogging different from writing in diary? The biggest difference is that blogging is much more than a diary. Usually, a teenager treats his diary like a book full of that she does not want to . It’s interesting that someone who writes in a blog a diary will probably write nearly the same information. I have a little sister, and sometimes I go online to read her . She writes about things like waking up early for swimming practice and not studying enough for her chemistry test. I was her age, I wrote about the same things, but in my diary. Then, after I had finished writing, I would hide my diary in a secret place because I was that my sister might read it! The biggest with blogging is that anyone can read what you write. If I was angry with a friend during high school and wrote something about her in my diary, she would never know! , if my sister ever wrote something bad about a friend, that friend read her blog and get a “cry”. There are also to blogging, of course. If I felt sad one day and wrote in my diary, “Nobody cares about me,” would know about it. However, if my sister wrote the same sentence in her blog, her best friends would respond and tell her how much they her. Blogs help people in touch with their friends and know what the people around them are doing.
