Actually i am now trying to redirect my sites to using affiliate ad's mostly from commission junction, rather then google, ads but also trying to keep the mix a little.

Also as other suggest the site i dont touch with ads is my business site Orion Networks, however all the others the whole point is to make money from them at some point, and as Vangogh mentioned about the forum here it is easier for people to swallow ads if they are there earlier rather then just happen to appear sometime.
