The bigger you get the more you should focus on selling your ad inventory directly. You can make much more money with direct advertising than with AdSense IF you are big(and interesting)enough.
Any tips on how to accomplish this would be appreciated. The one network I've looked at where you can sell your inventory doesn't seem to have a single publisher on it that is outperforming my AdSense earnings.
