About one in five kids between the ages of 12 and 17 keeps a blog, and twice as many read them. Blogs can lead to cyber-bullying and raise concerns about about a young person’s safety, reports The Christian Science Monitor, but there are also plenty of positive, educational ways for young people to use them. While students experiment with what to disclose and what to keep to themselves, schools struggle to find the line between protecting students posting (or being posted about) online and censoring them.
