The Times online has an article on Google’s advertising power which details Ebay’s pull of their ads. I can personally attest that not many folks hit those ads.
I’ve been running adsense in the sidebar a month and a half to see if I could earn enough cash to increase the bandwidth here, since I’m pulling in a couple thousand visitors or more a month now. Last month I earned a whopping $0.54 …. so — Google you can keep the check, thanks, and since I never liked the look of the ad strips, goodby adsense.
