World's Smallest Political Quiz.
It's surprisingly good, despite being very concise. I got confirmed I'm libertarian at heart. (Though I simplified my standpoints a little.)
People whose writings I like consistently turn out to be libertarians.
I'm against making people responsible for their own pension, privatizing welfare or blindly reducing taxes without first specifying which expenses you're going to sacrify.
Maybe the test is a bit too simple or too American?
The (longer) test at http://politicalcompass.org/test puts me in the exact center of Libertarianism. :-)
