Social Networking Websites allow you to get in touch with other people and create groups and communities in cyberspace. Through these websites you can communicate with other people who are interested in the same things as you.
The most popular today are FaceBook, Hi5, MySpace and Bebo. These websites allow you to create an on-line profile where you can share information with the rest of the website's users. Others Social Networking Sites such as Second Life offer you the ability to interact in an unlimited number of ways in a three-dimensional virtual world through avatars.
The information that people share on their profiles is usually about their education, where they studied, if they are in a relationship, what their general interests are, and what sort of people they would like to meet. Most websites also allow the users to share photographs, videos and music-playlists through their profiles, as well as blogs, which are electronic journals.
When using such websites, be careful of what information you put online. Everyone can see it, even people you don't know. The information you put online also becomes property of the website, so be careful that you don't put too much information! You never know who may be viewing your profile. When using such sites, you should be just as cautious as when communicating with strangers in the 'real world'.
