At DEMOfall 2006 - Buzzlogic
One of the most interesting product at the show. It helps identify influencers in social media such as blogs, wikis and forums. It allows marketing and communications professionals to track and measure the impact of their actions. The visual looked very cool in the demo I saw. Have requested a beta version of the product to demo to others around the company.

I can imagine very diverse uses for this product. I am convinced that this product will evolve very quickly into other markets.
