The Atlantic - Covers politics, current events, has a lot of feature articles about social issues, tremendous variety, and has some of the best writing you'll find. All of their bloggers are good, and run the gamut from libertarian to progressive, to an interesting blog about linguistics - the others focus primarily on politics but are free to and do blog about other stuff. The magazine is a monthly and well worth it.

The Economist - No better non-BBC magazine/website for World news and analysis of all kinds of things from a moderately conservative British point of view. Probably the best weekly news magazine in the world.

Ars Technica - Computers, technology, science, games, you'll find a very wide variety of topics including, occasionally, moderately editorialized articles on politically related stuff, but almost invariably it has to do with technology directly- technology is what the site is about. You'll get stuff from game reviews, to some of the best in detail analysis of CPU architectures on the internet, to relatively in depth posts about recent scientific studies. Quality ranges from decent to "wow".
