No. Just serving ads to already indoctrinated is of little benefits. You are better off serving them to people who are actively researching new stuff in an attempt to indoctrinate.
Or in Google internal ad selection engine terms: "Smart Ass" is an idiocy, the old "Dumb Ass" relevance based engine provides significantly higher ROI to most ad placers and websites.
