Rosenfeld and Morville's Polar Bear had an enormous success, and in the late 1990s and early 2000s the practice of information architecture was usually syn- onymous with designing Web sites for the World Wide Web. As 2000 became 2005, things were changing again. Users were entering the scene as producers (or prosumers, as they both consume and produce information), tagging was all the rage, and personal and home devices were starting to redraw the bound- aries of what computing was. Even though a persistent thread kept it tied to the creation of Web-only con- tent, which was (and is) especially true if you move into LIS-connected IA research and practice, a few individuals, people such as Adam Greenfield and Peter Morville, for example, started to consider that this was a limitation with little rationale behind it. Users were becoming producers, devices were on the move, and new problems 2000s: Information
