How do you feel about personal data tracking for advertising purposes, and retargeted ads that follow you around the web?

In some cases, these can be helpful - offering you a discount for that thing you left in your shopping cart but couldn't quite justify, or showcasing additional options for products you might need, but that you hadn't even considered.
