Jennie's post on how her boys and girls play an online role-playing game differently:

... it’s been just as interesting to watch how the girls’ reaction to the game. After the boys became obsessed with it, the girls had to try it. They’ve all got their own files (accounts), but they do completely different things in the game. They’re also not as obsessed, asking to play far less frequently. When Kailee plays, it’s usually to walk around and meet people or to accomplish a specific goal. Today, she met King Arthur and Lancelot, and she’s trying to save Merlin. She’s not interested in armor or fighting, but rather she likes solving puzzles, exploring, and talking with others. Whereas the boys talk in the game in order to accomplish something, boast, or trade insults, Kailee will talk to someone just to meet them (which was a whole other parental discussion we had with both kids). While it’s a generalization within a game that has thousands and thousands of players, the girls definitely aren’t in it to fight.

Labelling the four player types abstracted, we get achievers, explorers, socialisers and killers. An easy way to remember these is to consider suits in a conventional pack of cards: achievers are Diamonds (they're always seeking treasure); explorers are Spades (they dig around for information); socialisers are Hearts (they empathise with other players); killers are Clubs (they hit people with them).

Can we map these to blogs and other social software too? Traffic seekers, knowledge seekers, friend seekers and spammers?
