I am always mystified by the level of attention applied to the Doomsday Clock. The organization behind it seems to be staffed by serious (TM) people so there is probably some amount of analysis behind their proclamations but to what end? What is the difference between 85 seconds to midnight or 100 seconds or one hour? All sound pretty scary to me so I can't quite differentiate if I should be more scared (by how much? to what end??). This really seems like the power of storytelling (the clock metaphor is really striking) over any real substance.
The only indicator I would take somewhat seriously would be NORAD's DefCon if they would declassify the real time status and even then I would only consider it valid for 59 seconds. Any site that claims to show it is fake.
