“The Yahoo logo design process represents the worst aspects of someone who doesn’t understand or accept that type design, typography, and graphic design in general are professions that benefit from years or decades of training. Mayer explains the process they employed to create the new logo. If I had attempted to present the reasoning she used to any of my graphic design teachers in college, any of the people I worked for at studios or on a freelance basis, or to a client who had hired me, I would have been laughed at and told to get real, or fired.
“Mayer clearly appreciates the expertise and insight of folks who write code at Yahoo, run the servers, handle human resources, and the like. But, apparently, sees graphic design as something she is equally qualified to participate in without domain knowledge. Steve Jobs also saw himself as a designer, but from the decades of stories about how he worked, he generally demanded iteration, and selected and guided the direction of interfaces, print materials, and products, rather than leaping in with his own design execution.”
