FT.com / UK - A deeper peeper: "A bigger privacy issue comes up this month as Google begins to sell 'interest-based' advertising - with material tailored to individuals based on their evident preferences and behaviour online.

When an internet user visits any website containing a Google ad, the visit will be recorded and used to compile a profile that will then be deployed to direct future advertising to the user. Anyone who, for example, surfs a number of sites related to do-ityourself projects will be noted as a home improvement fan and will begin to see advertising for paint and power tools turn up on all manner of sites."
