Print magazine + web: a great combination?

Foreign Policy magazine is out with a relaunched website with a selection of new blogs, one of them by Dan Drezner (see Undercurrent interview). According to the Passport blog, the objective is to create “a vibrant, daily online magazine of global politics, economics, and ideas.” What’s interesting here is where Foreign Policy is coming from. A very slow bi-monthly print magazine now has a website that is updated many times a day with instant analysis. The web has made such expansion possible for serious print magazines (The Atlantic is another example). Maybe the print versions of these long-form, analytical magazines aren’t as exposed to web migration as daily newspapers. Their “content” lasts longer. Could this print-web combination be a winning media format?
