Jason, regarding your first comment… Most of the Web 2.0 tools are features not applications. They are layers that help interpreting the information in context that is helpful to the person wanting the information. The Bureau of Transportation project I worked on for nearly two years had Geospatial Information Service (GIS) and layered maps, which had more rich information visualization that the Google maps.Understanding the need for various information visualization and presentation layers is important. Having the budget to do this is rare. Having designers and developers who understand this is also rare, but this is getting better.There is very little different with what people are labeling Web 2.0, but there are three components that are worth paying attention to. 1) Focus on helping people see information in ways that help them better understand it (combining the intellectual and perceptual receptors from the Model of Attraction); 2) Opening information for use and reuse based on people’s needs; 3) Developers beginning to understand rich interfaces, but there are still giant holes with understanding when to go this route, how to think about it, how to design properly for it, how to build it for use, and how to test it.
