We're basically, Engineer, Designer, Writer. The Writer is the newest person and a recent college grad, what her role eventually becomes isn't clear (marketing? design?) For some reason this makes me think of the TV show Castle with him showing up with a bullet proof vest that says "writer".
The next stage of growth is hiring independant contractors for specific jobs that need to be done, and when we start wanting to have full time employees, they can be located anywhere. People want to telecommute and we like the sort of github style management policy.
I imagine that once a year we'd all get together in the same place for an annual meeting. Its also quite possible that we'll end up getting outside investors and have to start living in the Bay Area or something like that.
