Make A Social Network From Your Phone Bill

http://skydeck.com/

Analyzes your phone bill and who you call the most to build a social network for you. It's supposed to uncover your "true" social network and help reduce your phone bill...not sure about that, but tracking client calls and how much time and money you spent on them can definitely help with expense reports.

What interested me about this product was the social network graph, being able to visualize your contacts, but I'm not sure this is part of the product -- anybody used it and know?
