Traditionally I'm a director, plotmeister, and actor in that order. These days I'm trying on the provider method, which to me feels like a 180 as it comes along with relinquishing a lot of creative control.
I'm something of a reluctant worldbuilder; I want to have a detailed, stylish world, but I don't like the idea of that world being owned by someone else. That's why I'm on such an OGC kick these days (following on my Creative Commons kick).
