hello, Peter. I like your reflections on IA, and especially the idea of the IA as a hub. IMHO we are a fragmented discipline that is arising from a need as people quest after what the "essence" is of a good site, and how "good site" is defined. Today we hear that graphic designers are "IAs", creative producers are the project hub, and usability engineers are flying the "user" flag high. They all remind me of the blind men and the elephant - each has hold of a valid piece, but none see the whole.
