How to Ruin a Great Design talks about how designers in London are letting things slip. Before, London's street signs were well thought out, but now these signs are lacking in practicality and hard to comprehend. The photo of the Diverted Cyclists sign in the article is a great example. Making the "D" too big makes it look sloppy and again, makes the sign hard to comprehend. These designers are trying to "refresh" these signs, but all they are doing is making things worse.
