Hello All! I went to TEDx Cambridge a couple of weeks ago and there was a great presentation on what the meta data from your emails, through a range of time, says about you. If you're curious, you can download the app (called Immersion) Deepak and Daniel created for free. It accesses only the TO, FROM, BCC/CC, and DATE fields and generates a network map of who you've been talking to, how your email usage has fluctuated, etc. It's amazing how many inferences can be generated from just these few email metadata fields.

You can check out the video of their TEDx talk here: http://www.tedxcambridge.com/portfolio-item/deepak-jagdish-daniel-smilkov/
