It’s cool, and 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 bloggers are teens who’ve been logging(进入) onto sites to discuss anything in their lives. Many of today’s teenagers are not afraid to openly discuss everything in their lives. Teens complain(抱怨) 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.
