Thats very interesting.
But for many Americans this is too much. They see Google as trying to profit from their private data and (more important) see it as destroying privacy.
My point is, if ask for privacy... thats halt not possible anymore in the www.
Evey information gets somewhere filtered, collected and stored in massive servers.
If want privacy, then avoid the I-net.
Soon, you use it - your privacy is gone.
