GET requests are still exposed in URL per se! Rated 5 out of 5 stars
Working towards privacy is a great idea and MUST HAVE. But until those sites which wish to cater to the privacy minded cease pandering and actually-not-reveal search terms AS part of the URL SSL is of VERY LITTLE value
To further enhance privacy devalue yourself to evil engines like google who profit BY privacy violation. Install the "Track Me NOT" firefox extension to have it conduct interweb searches on your behalf.
Privacy is an arms race... once the sheeple are awakened to the DANGER the pro-privacy army grows all the stronger.
