Are you at all concerned with what Google knows (or may come to know) about your search history, and therefore yourself?
Google has a “Do no Evil” motto and I would love to believe them. At this stage all seems to be going well and I am happy for more competition for Micro$oft in any form. Google are really it (although Apple are making a comeback of sorts and there is the whole creative commons, gnu, and open-source battle still to come) for keeping MS real and I praise them for it. However as Google has become the search engine they have an enormous potential for misuse or even outright abuse.
What the hell are you going to do to keep your paranoia in check?
Information on protecting your privacy after the jump
Just to ensure that they don’t have access to any more of your search history than you want them to there are a number of relatively simple steps you can follow so that all google searches are sent through an anonomysing proxy. You can find full steps on how to configure your Firefox browser (you’re not still using Internet Explorer are you?) to do this automatically just for Google searches, leaving full speed access for everything else.
