And how much do you trust google/facebook? Because it would be trivial for them to link your logged-out behaviour to your account if they wanted to (via cookies and other means). Using a separate browser might help, buy isn't s guarantee. I'm not trying to be paranoid here, just pointing out that there is a lot of information which we make available to Google. If they wanted to be evil, it would be.very easy. I don't think it would tale much more to link this to your credit card either (eg via amazon/PayPal) by which time all your activotes ate there to see. Again, not being paranoid, just pointing out we live in an info-rich environment. Your only way to avoid it is to go totally over yhe top in avoiding leaving any trace which most of us are not prepared to do.
