Penny Arcade's Mike Krahulik makes a point about working with experts...
I don't have the skills, and I don't really understand animation, and so I feel like I would be stepping on toes if I laid out second by second what they need to be doing. Honestly I prefer when I'm collaborating with somebody who has a specialty, I like to give as little instruction as possible, because the whole reason that I'd be working with them is because they're good at what they do.
Would that more people understood that principle.
