Does this MSN Behavioral Search Matter?

Read the latest from MSN about its Behavioral Search, in recent MediaPost interview.

It’s interesting that behavioral search produced CTRs up to 76% higher than before. This is still based on whomever signs up for Passport. Call me ignorant, but this seems like a small and maybe even unrepresentative group. Let’s say it is better than NOT having a group who self-reports age, sex and even more about their interests. Is it valid to connect the interests and searches back to these profiles for people who don’t participate in Passport?
