When will segmentation end?

I was just looking at my earnings for last month. My blogging buddies have always tell me we can still do well without PPP. At one time, I wasn't convinced by that but not anymore. Looking at last month's earnings, I had done well at LoudLaunch, Sponsored Reviews and even Smorty. The rest of the networks had also helped to meet my target, which was great. It is disappointing to see only 31 opps out of 203 opps... what on earth is going on huh? Why are advertisers letting their opps rot away, I wonder? When will segmentation end?
