Given the furor over Ron Paul and what he means to the Libertarian cause, I thought I'd list some of the libertarian-oriented resources I've encountered in the last few months that have influenced my thinking.
Given my bent, these are sites or organizations that do not seem to reflect the Ron Paul wing of the party, but what I would consider a more "mainstream" libertarianism, if there is such a thing.
The Cato Institute podcast
These are podcasts of Cato events where speakers present a topic at Cato, often based on a book they've written, then one or more people spend an equal amount of time criticizing the main speaker. This is criticism in the true sense, in that the commenter may be supportive or may be very critical of the speaker. I find this is a refreshing format, and am unaware of (but would be interested in hearing about!) any other organization that presents subjects in this manner.
An amazingly informative economics podcast with a libertarian bent. Economics experts are interviewed on many different subjects that are accessible and important.
The Volokh Conspiracy blog
Libertarian law professors who cover all sorts of subjects.
Cafe Hayek blog
Blogging by Russ Roberts (who does the EconTalk podcast) and Don Boudreaux. I find it very informative, though I do cringe when they get into commenting on politicians. It seems like economists understand a lot about how the world works, but tend to be somewhat immature when it comes to politics.
Marginal Revolution blog
Tyler Cowen and Alex Tabarrok are extremely thoughtful economists with some very interesting things to say.
I'd be curious to find out about other such resources...
