News + Op-Eds
Opinion Journal is the conservative Wall Street Journal's op-ed on the web. For more liberal opinions, there's the New York Times or the Washington Post. Periodical equivalents for the two views can be found, respectively, in National Review/Weekly Standard/American Spectator/Commentary and the New Republic/The Nation/American Prospect/Progressive (Slate and Reason offer contrarian views to the partisan dichotomy). A voice of moderation is provided courtesy of The Economist Global Agenda. For a hodgepodge more focused on the humanities, Arts & Letters Daily is a good read. I usually get my home news from the government bugle, The Straits Times, and world news from either the controversial Google Newsbot or the WorldNews Network. I like the Atlantic, Harper's, and the New Criterion enough to have print subscriptions, although I would also read the New Yorker were it published less frequently.
For commentaries focused on economics and finance, the Economist is second to none (followed possibly by the Financial Times); Economic Principals is a nice weekly. Bloomberg has good columnists on a variety of financial issues as well. Euromoney, Project Syndicate, and vox also peddle economic policy commentary. For financial market commentary, I like the MSDW Global Economic Forum; for global political commentary, try Foreign Affairs' Background on the News, the American Interest, or Foreign Policy; for tech news, CNET News and TechDirt are probably the best.
For a laugh, I go to either Garry Trudeau's Doonesbury, Wiley Miller's Non Sequitur, Charles Schulz's Peanuts, Randall Munroe's xkcd, or Jorge Cham's Piled Higher and Deeper. The Onion is also great news satire.
Video + Radio + Podcasts
For home radio, feeds that interest me are Symphony (live feed here) (classical), and Class (live feed here), (Contemporary). Other web feeds can be found at Classic FM (Classical, London, England), WDAV (Classical, Charlotte, NC), Classical Music America (Classical, Detroit, MI) or KJazz (Jazz, Long Beach, CA). See also Pandora, for preference-mapped Internet radio.
Blogs + Bulletin Boards
A couple of blogs that are worth a surf now and then are Jeremy Iron's ArgMax, Gary Becker and Richard Posner's Becker-Posner Blog, Chris Blattman's Development Blog, Jim Hamilton and Menzie Chinn's Econbrowser, Gene Fama and Ken French's Fama/French Forum, Steve Levitt's Freakonomics, Nouriel Roubini's Global Economics, Brad DeLong's Grasping Reality, Willem Buiter's Mavercon, the Peterson Institute's RealTime Watch, Greg Mankiw's Random Observations, Dani Rodrik's Unconventional Thoughts (for economics views), Juan Cole's Informed Comment (for Mideast musings), FEER's Traveller's Tales (for East Asian commentary), and Tomorrow (for Singapore stuff).
sci.econ is generally hard and fast on various economics-related issues. There are some gems suggested by contributors, but not all posts are relevant. A smaller, but more specific bulletin board is the Economicsearch Bulletin Board.
