Wiki Sticky Wicket

How to find true North? I was surprised when I clicked...

(the edit read, "Stand still for 2 years, moss will grown on one side of your legs, this is North.")
Edit was rather quickly--errr--edited (Intellectual Darwinism?), but what if it hadn't been a "'How to' of the Day" link from the Google desktop?
Could have some very green lost hikers (Darwinism again).
