By 2008, the majority of Global 1000 companies will quickly adopt several technology-related aspects of Web 2.0, but will be slow to adopt the aspects of Web 2.0 that have a social dimension, and the result will be a slow impact on business, according to Gartner, Inc. "While it is straightforward to add specific technologies, such as Ajax or RSS to products, platforms and applications, it is more difficult to add a social dimension" Tuesday May 16, 2006 http://biz.yahoo.com/bw/060516/20060516005941.html?.v=1
