18．Web logs-"blogs"for short-are very popular among young people．Blogs are used to post thoughts，opinions，photos，and other materials on the web for the online community to read．Some bloggers have their own websites； others post their blogs on one of many blog-hosting sites．Blogs，a source of news，however，are not fixed communications．Postings can be added and replied to on a continuing basis．
While children may enjoy"blogging"，it can be dangerous．Online predators who search blog-hosting sites for potential targets，can learn personal information about the children who post blogs．Furthermore，predators are always able to contact the child who posted the blog by sending a message through the website．
Parents should be careful that their children don't get into any danger．To protect them，they can do the following things：
◇Warn children of the possible danger of blogs．Don't allow your children to post a blog．Explain to them that blogs can often be viewed even by people whom they should not trust．
◇Make sure your children know never to let out personal information on the Internet，whether through a blog，chat room，or e-mail．Even seeminglyinnocuousinformation-such as the mascot （吉祥物） of their school-can help strangers determine where they live．
◇Consider equipping monitoring software that will enable you to monitor how the computer is being used and what your child is doing on it．
◇Remind your children that they should not contact anyone online whom they don't know in person，even if the person has a blog that looks interesting to them．If your child has posted a blog on the Internet，check the content regularly．
◇Always get to know your children's online friends with whom they are communicating．
