On Liberty...arianism

I feel like having a friendly discussion about Libertarianism. I can't make any argument why such a discussion is particularly relevant right now. However, I have always been interested in Libertarian philosophy since I first learned about it. I know that Kent was and probably still is a Libertarian, and I think KScott has Libertarian leanings (but I may be mistaken). Anyways, I think it's been a while since we all had a hearty political debate, and since they're so fun, I thought we might relight our furnaces of political passion. I was hoping to start by having people put forth some initial thoughts for why they are libertarian or what they find to be the virtues of libertarian ideology. Perhaps, Kent, you can clarify whether you're an economic/consequentialist libertarian or a natural rights libertarian or both or neither. Hopefully from there we can move forward. If noboby bites, I'll put up some thoughts of my own concerning what I see are some issues with the ideology of libertarianism.
