MIT has created an interesting little tool known as
that compiles your personal Gmail metadata into a map of the people you contact the most.
The project, which became available to the public on June 30th, can access users' From, To, CC, Timestamp, and similar Gmail fields to obtain information and create a meticulous account of who you email and who they're connected to.
Essentially, you can mine your personal Gmail account for all the necessary information to create a web of who you contact the most and who you're connected to. It's an intriguing way to look at how our digital lives play out, especially if you're an avid Gmail user.
