Freedomain Radio some years ago while "surfing-the-net". This is a libertarian site, run by a true libertarian, but not in the political sense. Stefan Molyneux is a philosopher, or more correctly a libertarian philosopher (with a degree in philosophy), a sort of male Ayn Rand who uses modern tools to publish his message. He blogs, produces podcasts, he posts to YouTube and he writes books. He has some extraordinary insights that he shares with people through all these methods of publication. Need something to think about? Just spend a few minutes watching/listening/reading his always thought provoking material.
If you are in the Toronto area he will be attending one of our libertarian "pub-night" meetings in September. If you have Facebook - check this out, if not go to the Ontario Libertarian Party site and click on the pub-night prompt. Stefan is a local, from the Greater Toronto area and I think he is getting better and better at delivering his message. Here is one of his latest YouTube postings that gets to the core of libertarianism.
