Information Architecture Out of Fashion?

Before I took an all too brief detour into sound and tangible interfaces I was really quite interested in information architecture – I spoke allot about the topic here in the hinterlands of Taiwan and tried to put into practice all the theory I learned. At that time their was a tremendous amount of discussion surrounding IA and a vast library of literature. Lately having regained my interest and with some work coming I have set out to absorb any or all the latest thinking on the subject. But browsing all my old IA haunts have brought up little in the way of discussion, at least when compared to a few years ago. All I found were news announcements for various IA summits. Has the online discussion stopped? Have information architects all been forced to become business development managers or gone back to being librarians? Have sites that popularized social tagging made the information architect obsolete?
I’ll keep wading through all the bs hype about web 2.0 and ajax in the hope that I find something new to read.
