The latest scheme cooked up by the Department of National Intelligence (see Intellipedia, the free wiki for government employed security brown townysts) a social networking site geared towards keeping the United State's intelligence agencies and brown townysts working together.
In the words of Peter Sagal on
Wait Wait... Don't Tell Me!, "If you're an under cover agent, you'll soon be able to join A-Space, a new social networking site especially designed for people who can't tell anyone anything about themselves. It's every bit facebook and youtube for spies, but it's much much more. Only people with high level security clearance will be able to access this site; Members of the CIA and NSA will be able to friend each other, poke each other with fake poisoned umbrella tips, and post highly classified documents on each other's super fun walls."
