Steve Krug last night was his usual humble, humorous self with more than enough advanced common sense to please everyone. He spoke of kayaks (unexpected user behavior that’s not all that bad, like rolling over in a kayak), boxfish, and a missing chapter from the book: Why Your Website Should Be a Mensch. Indeed.
The one revelatory idea I remember was that, regarding accessibility, screen readers need to improve. It can be uncomfortable to think about not accepting full responsibility for improving accessibility, but he has a point: better screen readers will remove a huge burden from everyone else involved.
