Thinking politics across two axis

So most people think politics (at least here in Norway) in one axis, left to right. Conservatives on the right, liberals/social democratic parties on the left. But, something I just heard of (and had never really thought of before), is a two axis political "map", looking something like this (British version):



It's not revolutionary, but it's kinda interesting, because seeing things like this really illustrates some things.

The most remarkable thing to me is how parties that claim the greatest concern for personal freedom, when you think of it, often at the same time can be those wanting to control some of the things that are most personal in our lives, like choosing whom to marry. It also illustrates, at least I think so, the need for a broad spectrum of political parties. Here in Norway we are seeing that those parties found in the chaotic middle of the traditional left/right thinking are losing votes and getting smaller for each election, which basically means we are seeing a radicalization of society, and that is a very dangerous tendency.

So, what do you think? Interesting?
