“Design patterns are generally considered a good thing, but do they actually help run a user experience group? As a user experience group manager and an observer (and sponsor) of design pattern exercises, I’ve come to have serious questions about their actual utility.

Fortunately, there is a better approach: reaching outside the design group to solve the whole problem.”
Or, how anti-patterns become dark patterns.
