Chitika Anyone?

I started using Chitika last year. However I soon realized that their offering was only suitable for product related sites.

Darren Rowse waxed eloquently about Chitika. He is the poster boy for Chitika. His sites are ideally suited for it. What about the rest?

Is anyone, with non-product related sites, using Chitika anymore?

I wonder how many were actually able to cross the 100$ threshold with Chitika. The way I see it, it may account for a significant revenue for them
