The Top 13 Libertarian Web Sites

Here is a list of the 13 liberty-oriented institutions with the most web traffic. The list is sorted on the second column, which is the Alexa 3-month average reach per million users. The third column is the Technorati count of the number of blogs that link in. For sites where Technorati does not aggregate multiple inbound links from the same blog, I divide total inbound links by three, which in this context seems to be the usual ratio of unique links to unique linking blogs.

Ludwig von Mises Institute	76	1481	The leading American institute for Austrian economics
Cato Institute	62	2380	Arguably the most important force for freedom since its 1983 schism with the LP
Libertarian Party	38	700?	The only American political party advocating personal and economic liberty
Library of Economics and Liberty	27	903	No bricks or mortar, but a potent academic-oriented web presence
Future of Freedom Foundation	23	300?	Advocates the "free markets and limited government that made our nation great"
Advocates For Self-Government	23	150?	Pushes its Nolan Chart quiz and lists libertarian celebrities
Ayn Rand Institute	14	600?	Official institute for Rand's Objectivist philosophy
Independent Institute	13	491	Second only to Cato as a libertarian think tank; GMU's Tabarrok directs research
Reason Foundation	9	263	Libertarian think tank specializing in privatization, environment, and California
Adam Smith Institute	5	418
Institute for Humane Studies	5	150?	Founded 1961, moved from Menlo Park to GMU in 1985, focuses on scholarships
International Society For Individual Liberty	4	700?	Students for Individual Liberty (1969) merged with Libertarian International in 1989
Downsize DC	4	130?	The late Harry Browne's group for petitioning Washington

Honorable mention: the Electronic Frontier Foundation has libertarian sympathies and a huge web reach of 183, but is not a pure libertarian play.
