Well, you're correct - however, nobody aggregates the non-US userbase better, more accurately and so cleanly as FB - with 80%++ of their users non-US-based, they are THE goldmine for the NSA.

With the new FB policy office in DC, I am sure they are nice and comfy - as well as with their Security head from NSA-FB-NSA (along with all the other spooks FB has) -- its damn clear what is going on.
