Reliability of the information found on the Internet is often an issue. Anyone can post information on the web and lots of people do. Fancy graphics and creative web design can make any information look official, even if it isn't. Reputable sites do exist, but may be indistinguishable from the others. Another problem is that the Internet is constantly changing.
Web sites come and go.
Familiar and useful websites suddenly disappear or move to different addresses. Many of these new features require additional hardware and software that the user may or may not have. They also create a need for a faster and more expensive school Internet connection. The unpredictable performance of the Internet is another factor that can lead to frustration. The popularity of the Internet has helped to create Internet traffic jams that can seriously effect the performance of the web.
