Cameron Walker learned the hard way that sharing information online can have unintended consequences. In 2005, the sophomore at Fisher College in Boston organized a student petition dedicated to getting a campus police guard fired and posted it on the popular college social network Facebook. com. Walker wrote that the guard "loves to antagonize students.., and needs to be eliminated. " It was a poor choice of words. Another student informed school officials, who logged on and interpreted the comments as threatening. Though Walker claimed he was trying only to expose the guard’s demeanor, he was expelled. He’s now enrolled at another college and admits he made a serious mistake. "I was a naive 21-year-old," he says.
Creating a page on a social-networking site is now a cherished form of self-expression at universities around the world. Students use ad-supported services like Facebook, MySpace, TagWorld and Bebo to make friends, plan their Social lives and project their personalities. The most popular site among college students is Facebook, with more than 8 million members. A student’s personal Facebook page is usually a revealing, dynamic chronicle of campus life—one clearly not meant for the eyes of parents, teachers or anyone else older than 25.
But adults are taking notice. Sites like Facebook are accessible to nearly anyone willing to spend the time to gain access: teachers, school administrators, even potential employers and the police. Such online services can create the illusion of privacy where none actually exists. Facebook, in particular, was designed to emphasize privacy and intimacy. Only other users at your school (with the same college e-mail domain name), and those in networks you join, can see your home page. But determined off-campus visitors can persuade a student or alumnus to help them access the student’s page.
What happens when the identity you reveal to friends suddenly overwhelms the facade you present to grown-ups The results can be awkward—or worse. Photos from drunken parties, recollections of sexual escapades, or threats—all these indiscretions, posted online, have gotten students suspended or expelled, or harmed job prospects. In a couple of decades, a presidential candidate may be called on to answer for a college misadventure that he or she impulsively detailed in a blog entry.
Not all students want to temper their behavior. They point out that the Internet lets them express themselves and find like-minded souls. Still, adults aren’t likely to stop prying any time soon. That means students who use Facebook and MySpace have a new burden. The Web may seem ephemeral, but what you casually post one night might just last a digital eternity. While social networking represents a powerful tool for today’s students, they’re advised to be prudent. Even if they have no plans to run for president someday.

A:was caught posting threatening information online. B:abused and attacked the campus police guard. C:violated the rules when he created his own personal page. D:he logged onto the school’s official website without permission.

To get help, Internet addicts tired of their square-eyed, keyboard tapping ways need look no further than the Web for counseling. There is now an online counseling service at www. relate, org. nz for Internet obsessives. Just e-mail the details of your Internet-induced crisis and help comes direct to your inbox. (46)The new breed of cybertherapists see nothing strange about offering help through the very medium that is swallowing their clients’ free time and splitting their marriages.
Getting hooked on the Internet isn’t confined to a few computer nerds. It’s on the rise everywhere—and women are the most likely addicts. The old stereotypical addict was a young man who spent hours playing games, downloading software or reading messages on newsgroups. (47)Yet, the new image is of a young woman who fritters away hours e-mailing friends, buying books and CDs online, talking in chatrooms and looking for information for next year’s holiday.
Ingrid Parker, once a slave to Internet chatrooms, found her experiences so devastating that she wrote a book to help other addicts break the habit. (48) Her computer dream turned to nightmare when she sold up and moved to be with her cyberpal (who had just left his wife), only to be told a week later that the couple were getting back together. The heart-breaking turn of events gave her the motivation to control her addiction—and write the book Caught in the Web.
For Ingrid Parker, anyone who is married or in a sound relationship should not really be spending hours talking to someone else and ignoring their nearest and dearest. (49)While Parker provided her own therapy by putting her experiences down on paper, she recommends others take up the online counseling offer, or log off from the Worldwide Web gradually.
She said, "It’s like smoking. It’s not a good idea to suddenly go cold turkey. People often e mail me about the problem and I tell them to gradually wean themselves off and not to switch to a scheme where you pay per hour for online time. (50)If they break their resolution, all they end up with then is the same old problem plus money difficulties for the long hours they have spent logged in to the Internet. "
Of course, the Internet is definitely addictive but if you can keep it in control it has advantages, too. Using it can be a steep learning curve so it helps you become very quick at learning. Also there is a huge demand for people in the field of Information Technology (IT) and hours on the Internet are great training.
