Hat tip to cata.
Mory Buckman is eight people: the explorer, the worker, the gamer, the musician, the programmer, the thinker, the addict, and the person. (He's also not neurotypical.) It looks like a fascinating case study of Hansonian "model yourself as multiple agents and make deals between them," especially because he's been doing it for over a year, he writes quite a bit of notes, scores himself, and has regular conferences between the personalities that are posted to the blog. I haven't read enough to provide any intelligent commentary, but wanted to raise it to the attention interested in that sort of modeling.
He wrote Gamer Mom, an adventure game about convincing your family to share an experience with you, which is a design masterpiece (but also fairly depressing, so don't get too involved unless you're willing to take an emotional hit).
We've been doing this for years, but it doesn't seem to have changed our overall effectiveness at all.
The comments on the code for Gamer Mom are really interesting.
Dude really likes his Legend of Zelda; but as the comments go on, one begins to see his family reflected in the game.
(Also, the multiple modeling sounds like a huge time sink.)
