Key quote:

It annoys me on a personal level to see big Websites from rich companies violate usability principles that have been known since my first studies of Web usability in 1994. Considering that the return on investment from usability is usually around a thousand percent (the gains are ten times the expense), it simply doesn't make sense that so many designs still ship without any user testing, and that so many companies still have no usability staff. I am impatient because I know that things could be so much better and I don't see why people should continue to suffer frustrations from difficult design.
