Some people really take privacy to the absolute level – even going as far as confusing Search Engines

This FireFox Addon seems to represent privacy concerns at its most extreme -

   but then again, maybe after the revelations regarding the Government tracking search records it may not be so extreme after all

The Dangers of Searching on Google (Video)

http://googlonymous.com/

When you make a search on Google, your ip address, the time, and what you searched for is stored in their database forever and this information can be used in a court of law against you. Google will willingly allow authorities to consult their database, they already did as you can see in the video below. When you search on Google through Googlonymous, it is Googlonymous that goes on Google and does the search for you, the only ip address that Google will see, is the ip address of the server of Googlonymous. Googlonymous does not keep any record who searched for what. So this way, it is completely impossible to retrieve your identity. You can search for whatever you want without a care in the world, 100% anonymously.
