Check this out. This is smart. And a nice way for my to tip my hat to someone as I am browsing their site, but not necessarily interested in the ads that adsense shows. A lot of times I'll click on an adsense ad on a blog, so that the blogger will get some revenue. I don't usually do it unless I am somewhat interested in the ad. But, now I can change the ad to whatever I want it to be. Nice.
