I.T. is a huge field
I'm in desktop support, not web development. I'm at plenty of other tables already, and there are too many these days to sit at all of them.
Not knowing the mechanisms used or what they're named doesn't mean I'm unaware of their general effects and intentions. Targeted advertising is not unique to Google or the web. (*cough, couch - TECHREPUBLIC - cough*) Do you expect to get their services for 'free'? If you don't like their practices, have you heard you're not obligated to use them? Have you heard of ad blockers, disabling cookies, and other methods of reducing the impact of user tracking? I have, even if I don't know the exact names of some of these products.
