Comment Share your "encryption network" with Suckerberg! (Score 3, Insightful) 138
Right, that's exactly what you want to be doing if you are interested in encrypted communication... Share the list of other people who want communicate with you via encryption. That way the most intentionally invasive service in the world can build a giant graph of everyone who communicates via encryption. Then the NSA will know who to focus their efforts on just by who has had the most people download their public key or who is at the center of the largest clusters of connectivity.
This could possibly be countered by having everyone download lots of random people's keys. But only if FB doesn't require you to be "friends" before you can exchange keys.
The best way to counter it is to let all the sheeple use it, to give the NSA something to play with, while the astute "encryptionistas" ignore it.
