Forgetting how you use websites is crucial to understanding how your users will use your website. You need to get back to basic thinking or as Richard Saul Wurman would say "be dumb".
The only thing I have a grasp of is my inability to understand. That is why i'm more powerful than people who are smarter than me.
Wurman is a man of many talents but it is his specific insights into IA that I mostly know him for. His books on the subject are essential reading to any IA student.
5 Patterns from the Work and Life of Richard Saul Wurman
Dan Klyn has kindly collected Richard Saul Wurman's IA patterns and created a succinct list:
- Hats - order encodes meaning
- Sandcastles - what > how
- Gathering - apperception
- Tango - terror + confidence
- Dumb - expertise expires
If you are new to IA, this talk is a great introduction to key concepts but also introduces you to the man that started it all.
