Joshua Porter on the importance of copywriting in interface design:
There is nothing that makes or breaks a positive experience more than the simple set of words that you choose to communicate with. In a world in which we have to simplify as much as possible, nothing matters more than the small vocabulary you end up with in your final work.
Yet, there is no shortage of established applications that are still underestimating the power of words, under the illusion that pretty pixels and fluid animations are all that matter.
