Joe Kraus, one of the co-founders of Excite, and new blogger has long been rumored to be working on a new wiki tool. Today at the Web 2.0 conference Joe finally unveiled JotSpot, a new type of wiki that they have named an "Application Wiki". JotSpot appears to be not only an advanced wiki, but it also moves the predominantly text-based wiki toward being able to handle structured data and web application development.
