Maybe instead of Google coming out with more and more AdSense formats you can choose from, maybe they should make it so you can simply specify the size of the ad, and then they handle the logic on the fly to determine how many ads should be displayed (and of course display them). Because no matter how many ad formats they give, they will never fit 100% of the time for people. That and the ability to report per domain would be nice too. - Shawn
Technically I think they perfer you only use it for the domain you verified so they would not really consider domain reporting, I say perfer because they dont outright ban putting your banner on other sites.
Ah, I have ads without channels somewhere that I cannot find for the life of me. Domain reporting would be a huge help.
