Google Adsense Referral Program Launched

I mentioned the Google referral program yesterday, as it seemed that referrals to adwords were on the cards. Maybe they still are, but the adsense referral program has launched. A sample advert can be seen on the right of this page. I'd be more interested in seeing the adwords referral program launch, but if the adsense one brings in revenue who am I to complain :)
