Do you think that your activity on the Web is protected and anonymous? If so, you might be surprised to learn that Google (GOOG) has a new feature that nicely analyzes all your searches for the last few years -- possibly coupled with details about the people in your address book and your online purchases. If you have a Google account, you can access the whole thing at Google Dashboard, according to The Boston Globe.
Since Google is committed to avoiding evil -- which as I posted, means protecting your privacy -- you have nothing to worry about from the Google engineers and advertising specialists who do have access to that information. And what a treasure trove Google Dashboard provides!
