A few minutes ago i just received a call from yahoo asking me on how YPN! was working on my site. I told them good. They asked if i had any previous experience with others such as Google Adsense. I told them yes, and they asked me on how well YPN! compared to it. I replied, excellent, the CPC is much much higher. The only thing that needs improvement is the ad targeting, and the ... in every ad unit. I also told them a referral program would be great, along with ad links, and image ads.
