But if I want relevant ads don't I want them relevant to things I'm searching for anyway? I.e. advertise things on sites (and sections) where I'm looking for that category anyway.
There's no need for 'targeted' ads that follow me around if the ads are in the places I expect when looking for something.
Content providers should be ensuring they display quality and relevant ads, not relying on 'other' services to come find the consumer.
