The brightest people tend to be the ones who don't read -- they think they know how it SHOULD work or that they'll figure it out. So they experience the most frustration and sometimes cause the most re-work. (Often it's chief execs in companies who charge ahead without knowing the underlying details that could derail them, and all the little people have to run around and try to make up for it).
Once a technology is familiar to people, they tend to assume everything similar to what they know will work the same. It doesn't. That's why you threw them a curve ball.
