Web Logs

Instead of passing notes in class, teens are now sharing information on their Web logs, or blogs. A study showed that one in five teens in America has a blog, and about twice as many read them.

But some schools have prohibited (禁止) students from blogging on school computers. Other schools have tried to prohibit teens from keeping online journals even at home. But many teens say the journals are a great way to express their creativity. They maintain that a ban on blogging violates (违反) their right to free speech.

Blog critics say that kids don't know about online safety and that it's imperative¹ (必须的) to place limitations on students. They shouldn't post private information about themself, and they don't have the right to post someone else's secrets.
