Brian just implemented a new revenue sharing system over at Blog Engage-
Members can add their Google AdSense publisher IDs when editing their profile information. So on the pages displaying your article submissions, any clicks on those Google ads (at the top of the page) count as cash in your AdSense account. The more (quality) articles you submit, the more likely you will earn money. Pretty cool, right?
If you're interested in participating, you can find more info here.
(And if you want to earn even more, check out this post!)
