Tom Woods may not have been the individual that got me into being a libertarian but he has greatly expanded my knowledge of libertarian principles. He runs a daily podcast where he discusses various issues of libertarianism ranging from the Fed, Austrian Economics, First principles and so on. While some of the topics are deep there are a lot of very interesting and topical issues that are definitely worth learning/knowing about. He has also written a number of books on the recent recession, libertarianism and economics. If you are looking for deep insightful thoughts and discussions on current events, liberty and economics look no further.
