Google bought JotSpot, and it sorta disappeared. Word is that JotSpot will re-emerge soon as Google Wiki. I’d love to see a widely accessible and usable Wiki.
With the exception of Wikipedia, most people don’t know what a Wiki is or how to use one. Ward Cunningham’s Wiki develops the ideas of Hypercard and Vannevar Bush’s As We May Think.
Wiki is a great way of working together, although it tests the strength of the social contract. Even now companies are editing their own Wikipedia entries. At any point of controversy, the process of using a Wiki is stressed. However in certain kinds of small work groups, the Wiki is a great tool.
