The amount Google keeps from AdSense revenue used to be 17% of total revenue, now it's 5%.

Well that's just plain false. Federated Media outed their average take on a conference call about 2 years ago. It was briefly discussed on this forum. If I remember correctly, Google was keeping somewhere between 35%-40%. Not sure where you got your number.
