You don't have to be a "Secret Squirrel" to be concerned about Google tracking your online searching.
Here is a quick and easy way to use Google but not get tracked: http://www.scroogle.org/cgi-bin/scraper.htm
The following is a quote from their site: "Not only does Google scrape much of the web, but they keep records of who searches for what. If information about your searching is accessible by cookie ID or by your IP address, it is subject to subpoena. This is a violation of your privacy. Someday Google's data retention practices will be regulated, because Google is too arrogant to do the right thing voluntarily. In the meantime, you should not be leaving your fingerprints in Google's databases."
"There are other proxies that can protect your privacy on the web. Almost all are general-purpose proxies that cloak all of your web activity behind an IP address that is not easily traced to your service provider. One is Anonymizer.com. A possible problem with this one is that the founder, Lance Cottrell, has connections with the FBI and the Voice of America. It also costs money for a reasonable level of service. Another is Tor ["The Onion Router"], which is much more secure. But it is also slow, because Tor is a complicated system that needs networks of volunteers to run server software. Juvenile surfers from video pirates to rogue Wikipedia editors tend to clog free services such as Tor, which slows them down even more." Regards, OSOM - "Out of Sight, Out of Mind"
