I'm a generalist, and while I enjoy working with new technologies I no longer get a kick out of knowing every itty bitty detail inside out. I've worked in several industries in engineering roles (compiler design, geographic information systems, fabless semiconductor device production and testing).

I think writing a technical book could be very enjoyable for me. I'm good at explaining technical stuff, or so I'm told.

But I have absolutely no idea with the profile above what I could possibly write a book about that adds to the state of the art. "Wafer Database Schema Design For Dummies"?
