I've heard talk that running widgetbucks on my site is hurting me in relation to google due to some hostilities between the two. It seemed suspect, but its also interesting that Widgetbucks site is banned from Google's search results (google widgetbucks, you'll see) and no other publisher network I know of is. Am I being hurt? I enjoy the revenue but its not worth throwing out my adsense $$ or losing my google positions over widgetbucks money.
