I did this on Myspace, but maybe it really belongs here.
Types of myspace users, in accordance with the requirements for a Class Action lawsuit:
1. Numerosity: These myspacers don't care who their friends are, they just want to get as many as possible, and more than you. They'll befriend anyone who asks. They hunt down random bands to inflate their numbers. These are the people with more than 400 friends.
2. Commonality: These myspacers have friends who all have one thing in common, and it's attractiveness. These are the myspacers whose top 8 is comprised entirely of hot girls in provacative poses.
3. Typicality: These myspacers only collect friends who are their friends in Real Life. Accordingly, they have under 100 myspace friends. They consistently decline to approve random guys who hit on them with friend requests. Their myspace friends are the same type as their RL friends.
4. Representation: These are the myspacers who got talked into getting a myspace account, but who make no effort to collect friends or update their profile. You recognize these because their profile only inform you that they're a Sagitarius, and they have no photo. They might have only one friend, Tom. They are only minimally represented as a ghostlike silhouette.
