There was just an IA session today at SES San Francisco (see blog report [bruceclay.com]) and one of the points mentioned was this:
SEOs confuse architecture and construction as the same thing. You end up with the mental model of an SEO or a tech team, not the mental model of the user.
This is a point I made earlier in this thread, and it's ESSENTIAL. Because Aaron and I know that people will come into to the session expecting to hear about the technical aspects of site construction - url structure, what platform to use, etc - we will cover that, but as an extension of the main topic.
The main drive of Information Architecture is turning a visitor into a user, and that is my focus. Here's a link to our session description. Information Architecture at PubCon [pubcon.com]
