Tracking the entire world

NNDB is tracking the world, and it is both creepy and fascinating.

NNDB is an intelligence aggregator that tracks the activities of people we have determined to be noteworthy, both living and dead. Superficially, it seems much like a "Who's Who" where a noted person's curriculum vitae is available (the usual information such as date of birth, a biography, and other essential facts.)

But it mostly exists to document the connections between people, many of which are not always obvious. A person's otherwise inexplicable behavior is often understood by examining the crowd that person has been hanging out with.
