Glenn Beck showed the Nolan Chart on his show on Friday. That's great! People do need to find where they are, politically. Unfortunately, his website doesn't point you right to the quiz. It's located here: http://www.nolanchart.com/survey.php
However, the home of the Nolan Chart, nolanchart.org, is currently being obliterated by web traffic (possibly specifically to prevent you from taking this quiz and finding out you aren't who you thought you were).
So here are some other ways to take the Quiz.
On http://www.theadvocates.org/, they use The World's Smallest Political Quiz to determine a rough estimate of where you are, politically. It's not as precise as longer tests, but it's better than nothing.
Additionally, The World's Smallest Political Quiz is also available as an application on Facebook. You can find it there by searching for it.
You can learn more about the history of the chart and its uses at http://en.wikipedia.org/wiki/World%27s_Smallest_Political_Quiz
Encourage your friends and family to do it. I've even busted out the WSPQ at a party once, when people were half-drunk, and had people take it (one even scored a 0/0). We made it a game and it was fun.
So, take the quiz, and get others to take it, too.
