I know that it's kind of ironic to use blogspot for posting about being careful with giving data to google but I have the strong hope that others can resist :)
If you are a Firefox user there is a new helpful plugin with the accurate name Track Me Not. That plugin continously sends random search requests to major search engines and thereby hides your personal search requests for Viagra, Penis Enlargements and Porn :)
Enjoy your new anonymity without being worried if the plugin sends search requests like "taliban" or "terror camp" as long as you don't want to travel to the US :)
Thanks for following.
