Social Networking
A collection of websites that allow people to join networks that allow them to 
1) Socialise with people who have similar tastes
or 2) Allow them to stalk the girl next door

Some examples of these sites include MySpace, Facebook and Bebo, each of which attract their own clique of people.

MySpace attracts musicians, emos, and stalkers

Bebo attracts children pretending to be adults, Irish college students, and stalkers

Facebook attracts people who have nothing better to do with their time, namely stalkers
