What’s a blog? A blog is a personal online diary(日记). It’s cool, it’s hot, and everyone is doing it. People talk about it often. Sound like a fashion? In fact, It’s another trend (流行趋势). And the word “blogger” means a person who writes diaries online. Are you a blogger?　　
Many bloggers are teenagers who log (进入) onto websites to discuss anything in their lives. Many of today’s teenagers are not afraid to openly discuss everything in their lives. Teenagers complain about their parents and homework. They share diaries, post(发布) 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 worried about these young bloggers. Parents see the kids talking about how they got drunk last weekend and how they don’t like studying. They are using the language that is surprising to their parents. 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. They sometimes teach my kids bad words.” said Cara Cabral, a mother of two children.　　
Many teenagers and young adults know it’s not safe to use blogs on the Internet. They know they are putting information about themselves in a place where it can be seen by anyone. But teenagers are unwilling to give up these new communication tools that have become a way of life for many of them.
