You know though, it does seem like they could put some resources to filling in some of the blanks so when you click on a question mark on an open menu, you wouldn't get a red circle with a line through it. I worked in product development for many years and found documentation is always a pain, usually late, and not nearly as much fun as developing new features. It is important though for product acceptance and success.
I used to hire independent tech writers to make it happen. They could do most of it independently and only when necessary, they would briefly interrupt the crack designers to clarify something. They were much more efficient at creating good documentation. It takes different kinds of folks to excel at different type tasks. Usually my most creative developers were the worse at documenting.
