Rob Rohan has just started an alternative ad service that can be used instead or with Google AdSense. Kalator is a project that you can support Open Source projects (like CFeclipse) by showing adverts for them in your site, as well as (obviously) advertising your own Open Source projects!

I would recomend that if you haven't done so already, you sign up your projects or include it in your AdSense options so you can support the community!
