I just read this a few moments ago and realized this is one of my personal issues.
"Your marketing department:
Developers tend to look at marketing people with an evil eye. They get a bad rap for asking for things that are hard to implement or that don’t seem logical. They’re looking at your product like a normal person would. Their motivation is to position, promote, and sell that product to other normal people."
I'm curious as to what other folks think. Is this like the Engineer and Architect argument? I actually think that there may be some validity to this in kind of a left brain vs right brain type thing.
