I sometimes enjoy investigative reporting and news analysis published at some of the leading 'zines: The Economist, The Atlantic, Wired, Businessweek, Salon, The New Yorker. (Note: I never check these sites; I just occasionally click through from other, more selective sources.)
But I don't read enough stories to have found any that I'm confident are consistently driven by genuine curiosity. Imagine a webzine where stories are researched by a horde of gwern uploads and written by a horde Yvain uploads.
Can LWers recommend any consistently curious webzines/magazines, or at least some consistently curious authors?
For example: Glenn Greenwald shows some promise, but I haven't had time to investigate. How about Seymour Hersh? Greg Palast? TruthOut? FAIR?
I like Matthew Yglesias as a columnist who tries to understand & explain what's actually going on with current events / the economy / politics, rather than just battling for a side. At your level of engagement, I'd recommend reading his articles rather than his blog. I think the Moneybox archive is the easiest way to find them (since Slate doesn't seem to have a page which lists only his articles and not his blog posts).
