Recent research fromthe Pew Internet Project suggests that 90% of Americans aged from 12 to 17 usethe Internet, and 51% of those teens use social networks. However, there aremany possible problems with social networkingsites and the teenagers who use them.
    Apart from the social advantages, social networkingsites can be used to record school research, develop artistic talents andexperiment with other forms of subject creation. They provide a way to communicate with others who share the same interests and to gethelpful advice on ongoing projects.
Along with these advantages come some dangers.For example, most social networking sites are open to all, especially MySpace,which is the most popular social network among teens in America. It means that theycould be put in unpleasant and frightening situations.
A greater danger is that teens maybecome objects of the people with secret purposes. The secrecy of some socialnetworking sites makes it easy for dangerous people to find young teens and invitethem into dangerous conversations. It’s easy for them to pretend as teens and drawchildren into dangerous real-world communication as well. Then further hurtmight be on its way.
Another danger is identity stealing, which can happen when teens sharetoo much information about their names, dates of birth and locations.
    Therefore, it’s veryimportant to make sure teens are safe when they use social networks.
    Many of the same rules that work for online chat workfor these sites:
※ Don’tuse your real name.
※ Don’t give out personal information to people you don’t know. A lastname and a town
are enough for abad guy to find where you are.
※ Don’tbelieve that people are who they say to be.
※ Immediately end any communication that makes you uncomfortable andreport it to a
       parent.
Only if you aresure of your safety, can you enjoy the fun brought by social networking.Besides, trying to deal with all problems on your own can lead to terribleresults. Remember, asking your parents or school officials for help doesn’tmean you are unable to do anything but wiser than many others.
