Do you realise how
insane this comment is?
Full page ads are far more distracting than banner ads. You only have to look at the ad supported iPhone apps to see that.
Personally, I think the whole idea of "ad supported" software is an evil joke and why there are ads of any kind on the iPhone I just don't understand. I pay $800-$900 dollars for a device, I pay $70 a month for the privilege of using it, and it has ads on it?
People will eat dirt out of the yard if you present it to them the right way I guess.
