The legend goes that Google has hired all the really smart people in the field. How is it possible, then, that some of their popular applications have user interfaces that constantly violate widely known principles of usability?

I know it's a stupid question, but I feel annoyed by the combination of the claim that Google has super-smart staff and the fact that they have these novice mistakes in their interfaces. I mean, come on, who the hell still thinks that dialog boxes are a good idea?
