I just wanted to point one thing out, when we are all out there trying to drain as much money as we can, I want to know, show shows public ads on their site? Its a bit selfish if you dont, those ads been our charities running, which 90% of us will never donate to. So think! Click yes for public ADS
I really do not understand what you mean? (And I tried!) Is this just a try to get more links (which wouldn't real help as you have already 560 posts) or is there an actual question behind this?
Might just be how i see adsense working but does the fact that people are not displaying them mean that they are not getting the clicks hence they are not paying out for each one? Would that not mean they can focus their money where it is better needed?
What I mean is, if you display public ads when your ads are not shown, you are creatting clicks for charities which dont have to pay for the advertisement!
