google is spying on me (and you)

I don't know how this works, suspect it has something to do with cookies and other seemingly tasty things that are actually bits of confusing techni-code-whatever.

But Google is on the job, busily reading every email I send. Just to test it, I sent an innocuous note to myself from one Gmail account to the another . . .

Dear Belle ~
My dear, I am so disturbed about what is happening. It seems dickheads abound and there's nothing we can do to change course. Please share with me your thoughts on these matters.
Most lovingly,
Lynette

My sidebar links in the email I received from myself, each of which Google believes will be of interest given the text of my email, were more limited than usual, but included an outfit selling Labradoodle puppies and another selling wilderness homesites in Montana. Google hears my pain and responds with solutions. Despairing about the state of the nation? Get a dog and move to Montana.

This offends me on many levels, but one annoying example is that every conversation I have via email with my customers, all buyers of my antique furniture, results in a vast amount of linkage to others selling antique furniture. In these difficult times, I feel a bit proprietary about my longterm relationship with these people and the money I put into marketing my product. What right has Google to attempt to interfere with my business? (Yes, I could switch email accounts, but it is an enormous undertaking with an online business and, having done it once, I am most reluctant to do it again.)

Does this bug you? Am I hypersensitive in this era of Big Brother Bush and his band of wiretapping thugs? Do you think BushCo receives copies of this stuff in the same way AT&T assisted the National Security Agency in data-mining our telephone conversations?
