What is a social network? What are the dangers for children using such services?

In this latest article Computer Active explains all of the important terminology and current popular services among young people:

If chatter about social-networking sites and instant messaging (IM) bewilders you or leaves you cold, don’t worry. Opinion tends to be pretty equally divided as to their worth. At best, many detractors dismiss sites such as Facebook or Twitter or tools such as Aim and Windows Live Messenger as a waste of time. At worst they are perceived as a grievous threat to society and to our and our children’s safety.

For others, however, such sites and services are harmless and a part of everyday life. Join us as we examine this online phenomenon that always seems to be hitting the headlines. We’ll put the dangers into perspective and explain how you can protect yourself and your children when using social-networking services.

Social-networking sites are websites that enable people to publish and share information about themselves. Each member has their own ‘page’ on the site, usually referred to as a ‘profile’. Instant-messaging services are convenient communication tools that enable people to type messages to each other in real time. The main reason for their popularity is that they give people a quick and easy way to keep friends and family in touch.
