They develop interactions. Complex stuff requiring years of training and committment to very very hard work in a very competitive world. People who manage systems or networks or websites or groups of users, customizing the systems, building applications out of system functions and commercial apps, at the front line. Lots of secretaries fit into this category. They have the time and the patience to learn, and they understand the human systems.
Librarians turn out to be big end-user script writers too.
They connect the two worlds. At the intersection of any product and script writers, we need people who have a systems background, deep talent and committment, people who are driven to learn and grow. Look around you. People like Preston, Brent and Scott and John Baxter, Mason Hale, etc. As a case study, look at the FileMaker scripting interface, and then look at what Brent Simmons has been able to do with them.
