For the last six months, the folks at Aplia have contributed great current event content for the economics course. Every few days another posting brings the same formula of a essay, linked to more indepth readings or "research" that the students may do, and a few questions at the end for class discussion or assignment.
The ones I have read are extremely well done. I would only worry that they won't archive well since, even if Aplia will continue to provide these free, the links to readings are at the originators discretion. You can subscribe via RSS through Feedburner and have all of them sent to your reader (I use My Yahoo for that).
Try Aplia's "economic news blog, a place to explore current events that relate to your econ classes. (They're) currently beta testing this idea, so (they would) love to hear your comments. ... at firstname.lastname@example.org.
