WebSideStory has been positioned by Gartner Research in the Challengers Quadrant of the research firms' Magic Quadrant for Information Access Technology and has simultaneously announced a new product bursting with AJAX mojo -- a site search solution called Active Browsing (patent pending). Active Browsing allows any e-commerce site to integrate one of Web 2.0's enabling technologies, AJAX (Asynchronous JavaScript + XML), into their product search results. According to WebSideStory, Active Browsing increases speed and interactivity, and improves customer shopping experience in which shoppers are able to engage in "clickless browsing" -- the ability to preview additional product facets and "more like this" categories just by rolling their mouse over specific search results. In addition to WebSideStory, ZyLab announced today that it too was in Gartner's Challengers Quadrant, with DATAllegro, GigaSpaces, and Campus Management announcing their position in the Visionaries Quadrant, and Expand Networks and Plateau announcing their place in the Leader's Quadrant of the Gartner Magic Quadrant. Gartner's Magic Quadrant is a graphical representation of a marketplace at and for a specific time period. It depicts Gartner's analysis of how certain vendors measure against criteria for that marketplace, as defined by Gartner. While Gartner officially calls its Magic Quadrant a research tool, and "not a specific guide to action," many in the industry use it help narrow down choices, and companies use it to boost credibility for their products. The guide sells for a bit more than tickets to David Copperfield -- $495 -- and is available at the Gartner.com website. Maybe it's the legal department that really works the illusions, since Gartner also includes this statement: "Gartner disclaims all warranties, express or implied, with respect to this research, including any warranties of merchantability or fitness for a particular purpose."
