It's hard to do advertising well where the interests of all parties are aligned. I think Google did a very good job with this, since the ads it serves you are more likely to be genuinely helpful to what you are trying to do. Most Internet ad models revolve around interrupting the user--being blind to the user's goals and point of view. Compounding this problem is that users often find it creepy when ads do know about their goals and point of view. Someone needs to creatively disrupt the current "off-topic interruption" vs. "on-topic privacy invasion" ad paradigm.
