When is the right time to initiate a countdown?
	
	
		We've all got stuff that we look forward to, right?  Even in the chat room earlier, it was clear a few people were preparing for the phenomenon that is Snakes on a Plane.  Some other guy said it was 5 days to the release of [i]Dirge of Cerberus.  But when does anticipation become overkill?
When's the right time to start a countdown?  Does it depend on the magnitude of whatever it is you're looking forward to?  I remember Mandee counting down from 100 days to her wedding day.  So yeah, discuss.
