This is a textbook example of why it's never smart to hinge one's profitability upon the whims of another company.

I've been down these paths with Adsense, EPN, and others and I learned the hard way that affiliate programs and ad revenue can be booming one day and gone the next.

Now I only build PaaS and SaaS sites (not counting freelancing work on the side) and I'm a lot happier with a much more stable income from my web apps that is not dependent on the whims of anybody.
