I started listening to Stefan Molyneux when he was still making his podcasts while driving to work. He was at around #400 and I started diligently with the first. I never caught up, I stopped listening when I realized that he is hopelessly and irredeemably ideological.
His presentations were a little too verbose but fair representations of libertarian principles as they relate to various subjects. Still, I consider his work the best example of the problems of ideological libertarianism today.
He is, of course, not alone, he is standing on the shoulders of the likes of Rothbard, but Stefan represents best what I would call populist ideological libertarianism.
