This is only one of many types of so-called 'metadata' that NSA collects. What is metadata and how can it be used against you? They use it to build social networks that can identify you better than your DNA.

The NSA has been creating maps of American citizens' social networks

Why do they want to do that? What could social networks be used for in the hands of government? Consider:

Using Metadata to Find Paul Revere

How will such capabilities be used now? How They Hunt

Is it already too late?
