I want to take a slight detour from usable privacy and security and discuss issues of design. I was recently at the Microsoft Faculty Summit, an annual event where Microsoft discusses some of the big issues and directions they are headed.
In one of the talks, a designer at Microsoft mentioned two data points I've informally heard before but had never confirmed. First, the ratio of developers to user interface designers at Microsoft was 50:1. Second, this ratio was better than any other company out there.
