Other suggestions I'm surprised you haven't as of yet seen. America has several extremely well-written and well-edited magazines filled with quality writing. A strong but fun prescription to improve your reading acumen would be a subscription to the New Yorker. Need more words? Add one monthly dose of the Atlantic. If you're British, try the Spectator, as it'll be much cheaper than the American mags. (Not to be confused with the American Spectator, which was a crass vanity mag for Clinton-bashers.) Sure, it's Tory as hell, but it's still impeccably written and edited. If reading news is your thing, ditch the American tabloid newsmags (Time, Newsweek, US News & World Report) and read the Wall Street Journal, Christian Science Monitor, or the Economist. (The former two are daily papers, the latter a weekly magazine.) All three are pretty conservative, but I'd rather read well-argued conservatism than ill-argued social-democracy. (Because of that "well-reasoned" caveat, you can safely ignore the WSJ's opinion page, even though their journalism is excellent.) The New York Times is also decent, and definitely more palatable for me politically. But frankly if you just read the Op-Ed columns by Paul Krugman, Tom Friedman, Nicholas D. Kristof, and Bill Keller online, and the Today's Papers page at Slate, you've gotten most of the value out of a daily NYT. There are a few well-written hobbyist mags, too. If you're into cars, pick up Sports Car International, Automobile, or Car (UK) instead of Motor Trend, C-and-D, or R&T. If you're into stereo stuff, pick up Stereophile or HiFi News (UK) instead of Home Entertainment. If you're into more political stuff, The New Republic is a good magazine. If you're more right-leaning than TNR, sorry, but there really isn't a particularly well-written right-wing political magazine in the US. Also, check out reports by American NGO's such as Brookings. For free, try Slate, http://slate.msn.com.
Lots of brilliant people write for it, in a more informal format. It's about culture, world events, etc. For example, last month there was an interesting exchange between Strobe Talbott and Anne Applebaum about Russia's post-Communist transition and the Clinton admin's role therein. (Talbott is now head of Brookings.) I recently discovered Slate, but it's now my #2 daily read, after the NYT Op-Ed page. Sure, with magazines you won't get the punch of something like Ulysees, but then again, I personally never could get past page 600-something in that tome.... also, the shorter doses of verbiage of magazine articles and short stories might make following the stories -- and therefore perhaps better for learning the subtle nuances of usage.
