One person posted here a year or two ago that he dropped AdSense for selling his own ad space and increased his earnings x6.
I added a banner for a client on one of my sites. The amount of clicks I got is WAY beyond what my adsense account reports across all my sites together. Many ideas came from that experience, currently working on it.
