Re: Google and privacy???
So lets say you have visited XYZ marine store and now you do a search for marine parts. Becaue Google has tracked your using XYZ and XYZ pays Google guess what happens to your search results. No, you won't be sent to iBoats.
That sounds far more like a problem for iBoats than for me....
In fact if XYZ has what I am after, at a price I am prepared to pay, that actually sounds like a total non-issue, and I may be the winner.

(....and I suspect that iBoats probably is clued in to what Google offers and may be on board as well. So they may indeed come up in the search results.)
Before Google (et al.) I'd probably be using the Yellow Pages....and guess what....if XYZ paid the Yellow Pages, they'd have
EXACTLY that same competitive advantage.
As for it being in any way a privacy issue, (and you never did answer GA_Boater's question) I suggest that you get out a dictionary and look up that word....P-R-I-V-A-C-Y.
Your posts in these forums reveal more personal information and do far more to compromise your privacy than anything you have described in this thread would do...IMO.
I appreciate your concern for us babes-in-the-woods, but I really don't think that the "sky is falling".
