Web 2.0 and the new role of Information Architects

In the world of Web 2.0, the role of Information Architects are getting more important and complex than ever. What's been called social classification, ethnoclassification, folksonomy, freetagging and metadata for the masses have become the foundation for experience innovation.  Services like Flickr, del.icio.us and Furl are creating communal classification schemes by aggregating tags, simple metadata added by each system's users. The remarkable success of these services seems to up-end traditional thinking about classification about what IAs learned in school.  What lessons can IAs learn from Flickr, del.icio.us and the like? How is service design affecting the role of IAs? What about portability and micro-contents? What are the new skills required? I have prepared this presentation for an industry briefing, and if you'd like, it is available for viewing below.
