I really enjoy both the Economist and the New Yorker. They tend to take very different stances on the same issues, but both have really excellent long-form articles that I enjoy. I also recommend hobby magazines (like Shutterbug or Adventure Kayak) that fit with your interests.
I also tend to print anything substantial that I plan on reading. It's just easier on the eyes (though Firefox's reader mode and usejournal.com also help) and I can re-use the blank side of the paper for my notes. After that, it makes an okay fire starter.
I've also started subscribing to magazines and newspapers again. Most of the 'online' content I read is available in print form.
