How do I keep my privacy while using Google?

hubert.lepicki writes: I use Google all the time. I keep two GMail tabs open when I browse Internet (one is private, another corporate account), I use Google search and recently I switched to Chromium browser. Google's services are fast, easy to use and usually reliable. At the same time I know Google is tracking everything I do, I can see it in search results or their ads on web pages, that tend to match my interests. After recent article posted on private blog by Mozilla's community director (http://weblogs.mozillazine.org/asa/archives/2009/12/if_you_have_nothing.html), I started to...

The results weren't very helpful (what a supprise), so I ask you — Slashdotters: how do I stay anonymous to Google while using their services?
