Gmail + Google cookies = BIG EVIL
You probably know about Google putting up a cookie on your PC with an unique identification number until the year 2038 and this is not a big secret, though many do not understand completely what it means.
And this is also possible that you have a creepy gmail account on top of that.
Well, these two in combination gives Google (and many other governmental agencies, and we are not only talking about those from USA, but from other countries as well) possibility to track back all your searches ever made with Google :-)
Spooky enough for me…
