Links: Reason Magazine
There aren't too many libertarian magazines floating around - many of the older ones formed in the 70s, like "Inquiry" and "Libertarian Review," are now defunct. One of the survivors is "Reason," a monthly publication with (some say) a right-leaning libertarian slant. I catch up on it from time to time, though I don't have a subscription or anything.
The measure of any good magazine is how much it makes you think. In terms of breaking news, the various MSM do a decent job of at least telling people what happens around the world. What you receive from a magazine, supposedly, is entertainment, commentary, and analysis on topics that you thought you knew all about.
For example, a recent article in "Reason" focused on how ridiculously hard it is to fire a teacher in New York City. While we all joke about tenure, it's startling to see how bizarre the truth is. Here's the nifty illustrated chart.
