Sorry to keep pushing Tim Berners-Lee and the semantic web on readers, but something big is brewing in this area.  The siliconrepublic blog had some more interesting news about Berners-Lee and his theories about how linked data or the semantic web can help eliminate email spam. 

Our Linked Data Planet tradeshow coming in June in New York City will be the place to understand what the semantic web is all about.  There are other shows out there talking theory.  Our show will have practical applications on how linked data is revolutionizing the Internet.
