I was recently interviewed by CIO Insight magazine about Why Information Architecture Matters. I'm not sure I did justice to the topic, but at least I managed to put concepts like authority, credibility, and information architecture in front of 50,000 CIOs. Oh yeah, and I did mention Ambient Findability though I suspect most CIOs have neither the time nor inclination to actually read books.
Apart from everything else, I really liked your take on "usability" which, rightly said, has come to equate to quality. Sometimes it's exactly perceived what it is not. And that really kills it. I am also amused by the fact that the lack of interest or time is ubiquitous in all parts of the world :)
