I'd like to offer a view from the "other side".
I have a small web business and I use google AdSense (i.e. I pay when someone clicks on my ads which are shown on google searches).
I just want you all to be aware that when you click on an ad, it is not google who is paying Mudcat, it is the advertiser. Now if you have some interest in what the ad is selling, then great! Click away! That's the whole idea of having the ads there. But, as much as I want to support Mudcat, clicking just to click could be hurting small advertisers like myself.
I do think it's a great idea to have the ads on Mudcat. From the reports I've seen, this program does successfully produce funds for content sites that generally have no income.
So keep the ads, all I ask is that you use them responsibly!

(And just for the record, I recently had my ads removed from this program because I was getting tons of clicks and no sales. So I now just have my ads on search pages.)
