I'm not going to take it again just now, but I've probably posted my chart from this test a half dozen times across various forums, including probably even this version of 2+2 politics (just slightly to the right of wiiziwiig in the left/libertarian box).
I have two complaints with it:
1) It's been around a long time and as far as I can tell has never been updated. I think the questions were topical at the time it was put together, and the topicality made it somewhat useful. But the further removed the test gets from contemporary politics the more I think it just misses a lot by not asking relevant questions
2) It's always been obvious that the test is designed in part to promote the correctness of left/libertarian views. Not that I mind, I share those views. But I'm very certain that results tend to cluster towards the bottom left in a way that is misleading. Similarly, I recall the site posting charts where they plot where well known political figures are supposed to be, and I'm pretty sure their positioning is just entirely fabricated.

Pew Political Typology quiz I posted a while back (results
