How to Ruin a Great design response

While a bad design in regard to visual studies is not as drastic a social issue as this article makes it seem, it does prove a pretty interesting point. The small details in a design that might have been overlooked as unimportant could ruin the entire thing, however i'm not sure if I could agree with this without someone blatantly pointing it out and explaining what's wrong with it. Small mistakes can become distracting and could undermine the whole reason of something, for example a traffic sign. The author insists that there is a way of doing things for a reason, like having all the traffic signs in the same font and design. Which makes me wonder what he would expect from new ideas if the originals are so perfect. I actually like weird fonts and distracting set ups, probably not in traffic signs, but I do appreciate them in pop culture. An example of this would be DAMN. by Kendrick Lamar, an album with bold red simple letters on the cover and all capitalized letters and punctuation marks for the track list.
