Some acts of expression are awesome, while others suck, and one philosopher has a new theory about the difference. Using this theory as a guide, we look at some of the suckiest things that ever sucked in urban design, and the street artists and compassionate vandals who are trying to fight them. We use these stories to investigate how public spaces are becoming less free and more coercive. Guest voices include Nick Riggle, Leah Borromeo, Rowland Atkinson, Victor Callister, and Richard Rowland.
