A Flash of Design Insight
I read POET a while back, and I haven't been able to look at door with a "PULL" sign the same way since. I've also acquired the (they tell me annoying) habit of (over) analyzing my environment. I recently came across the above weirdness at the Pizza Hut franchise inside our local Super Target. It's a little hard to see, but the bar stools facing the window have a board mounted vertically in front of them. It sticks out as an anomaly in an environment obviously designed to be efficiently churned out by the thousands and lacking any non-functional detail.
I sat and stared at it for a good chunk of the 6.001 minutes it took to prepare my Personal Pan Pizza before finally realizing how it added to the usability of the space. Here's a hint: it has to do with the interaction between patrons on the stools and people outside. No? Ok, .
 The Design of Everyday Things.The name's changed (it was 'The Psychology of Everyday Things') but the song's the same. But you're read it, right?
 Only very badly designed doors need signs telling you how to operate them. Good doors have affordances that tell you how to operate them without the need for written language.
