Touchgraph
Fooling around with the Technorati API, I chanced upon Touchgraph. I know hyperbolic visualizations have been around for a while since PARC first published the concept, but Touchgraph is something else. I am amazed at the fluidity of the nodes. The TG GoogleBrowser gave me more information about my site than pages of standard Google results.
I have always been an avid follower of social networks and after reading Linked I became much more interested in scale free and social networks. Touchgraph makes me wonder if existing dating sites have it all wrong. I think the efficiency and accuracy of matchmaking can be greatly increased by combining social networks and visualization technology like Touchgraph. I may have to start a project to explore this.
