VisiWiki or the Visual Wiki is like visiting inside someone’s head. It almost provides a cognitive map of specific topics such as geography. I looked up Guns,Germs, and Steel and it was like wandering Wiki, You Tube, Google Maps, Flikr, and Yahoo without all the browsing time. The topic Geographic Information Systems of course brings up among other things, John Snow’s map of the cholera outbreak. It’s fun to explore and you can imagine what it will be like as it becomes more robust.
