I agree with you, this is an open source dig though, on publicly available information. The publicly released date for Osama's "death" was May 2nd. Palantir was "rumored" to have led to this, and immediately after their valuation grew exponentially. Palantir was started in 2004 with 2 million from the CIA and 200 milion from Peter Thiel and is now worth $20 billion. Something is a little fishy, they must be extremely important in all the intelligence community to have grown that exponentially.
LifeLog was meant to store data. However, the objective of the LifeLog concept was to take in all of a person's day to day life.
Palantir was founded the same year Facebook started and LifeLog ended, headquartered across the street from Facebook.
By 2008 Palantir was impressing GCHQ with it's ability to visualize massive amounts of data. No definitive links since there is almost no data on LifeLog, but I think Facebook and Palantir are two sides of the same coin.
