What’s the best way to get people to start buying ads on your site with adbrite?

I’ve used adbrite for a while now for my site http://nogamesallowed.com
and nobody has ever bought an ad on the site
is there something I should be promoting to get people to advertise?
(at the moment it shows a low # of pageloads per day, but that is just because I had taken the ads off and just put them back on yesterday)
