Now Tony Piro of Calamities of Nature
can't get enough credit for his review of various ad services. Does it tell you everything you ever wanted to know about internet advertising? Well, that would be impossible, and experimentation is always required no matter how much information you have. But I tell you what, anyone looking to get in on the ad game had ought to give this article of his a look.
But the main thing, whether you are even interested in learning about ads or not, is that Tony has done his webcomic pals a good service by putting together this article. I respect folks who give to the community like that, so HEAR HEAR!
