No libertarian blog discusses current events better than Reason's Hit & Run. Essentially a distilled version of Reason Magazine's viewpoints and style, Hit & Run focuses primarily on identifying and explaining the failures of government.
Hit & Run also features more overall content than any other blog on this list. A dozen posts or more constitutes an average day.
Rounding out Dietrich’s best-of list:
4) The Libertarian Standard ("home to arguably the best content of any libertarian blog").
3) The Circle Bastiat ("With [its] concentration of academic star power, this blog, which is hosted by the Ludwig von Mises Institute, stimulates its readers’ intellect").
Laissez Faire Club ("If nothing else, the LFC Blog is a pleasant alternative to the polemical, pessimistic rants of so many other libertarian writers").2)
1) The Beacon ("Unemotional yet unique, The Beacon is a must-read for all libertarians — young or old, monarchist or anarchist, Austrian or Public Choice. A delicate balance of positive and normative analysis, together with unrivaled consistency in quality, elevates this blog above the rest").
Dietrich also gives a nice shout-out to former Reasoner Cathy Reisenwitz: "the best new libertarian blog online is undoubtedly Sex & the State."

But not as useful as a crowdsourced list from you, beloved Hit & Run commenters! So since you've got another hour until the A.M. Links, let's hear your supplemental suggestions to the list above, preferably with some colorful prefixes in front of "tarian" to indicate differing viewpoints and emphases....
