The Internet joins us with people who you might be cut off from! LOL!!!
The Internet can also harm you if your not careful e.g. everybody uses chat rooms but not everybody who uses a chat room is a student. and it can be really easy to be tricked into befriending somebody who only wants to harm you if you're not careful on the Internet.
However, you can talk to friends on the Internet; and if you're a musician you can talk to other musican's on Myspace. If you are a writer like me then you can set up your own blog.
If you are a student there are chat rooms for course work and study such as Sparknotes.
