Tyler Thompson on Delta's boarding pass: "It was like someone put on a blindfold, drank a fifth of whiskey, spun around 100 times, got kicked in the face by a mule (the person who designed this definitely has a mule living with them inside their house) and then just started puking numbers and letters onto the boarding pass at random..."
Andrew Wilkinson on Zappos: "I checked out your new website and wanted to stab my eyes out with a sharp object."
Dustin Curtis on American Airlines: "Fire your entire design team, if you have one." (His original post was harsher but he has edited it since and I don't have access to the original.)
