     It's cool, it's hot, and everyone is doing it. People talk about it often, and friends tell other friends how

  good they look. Sound like a fashion? It's actually another trend (倾向): "blog". What's a blog? A blog is

 a personal online diary. The word "blogger" means a person who writes diaries online.

     Many of today's teenagers are not afraid to openly discuss everything in their lives. Teens complain

 about parents and homework. They share diaries, post songs from the latest bands and show pictures of

 theirs. They write their own poems, say something about their girlfriends or boyfriends and complain to

 each other or offer support. But mostly they just write down what they do every day. However, many

 parents are afraid of these young bloggers. Parents see the kids talking about how they got drunk last

 weekend and how they don't like studying. Besides hearing from their friends, teen bloggers also get

 messages from strangers. Most of the time, it's older men asking to meet teenage girls. "These strange men

 are dangerous for my kids." said a mother.

     Many teens know it's not safe to use blogs on the Internet. They know they are putting information

 about themselves in a place they can be seen by anyone. But teens are unlikely to give up these new

 communication tools that have become a way of life for many of them.
