Take a look at this little article written by another PayPerPost-er. He's written about the mild war going on over how to make money blogging - ie, is PayPerPost the wave of the future? I don't really know. Given the limited types of things that you can write about, and how very little effort using Adsense takes, I think a lot of people are pretty content to sit back and not really do anything, and collect little Adsense checks now and then. I think it's really us little bloggers, who don't have enough site traffic to get a lot of Adsense revenue, who benefit the most from PayPerPost - and someone with a lot of blog traffic is probably concentrating more on maintaining the blog and updating it than with looking for good opportunities. I think in general both types of advertising are going to exist side by side although I think payouts from Adsense are going to go down as people learn to ignore them just as they learned to ignore banner ads.
