You could outline any territory as a series of geos if the need ever  
arose. But I'm still not clear how we've gotten here. If I want to  
say something is in Ireland, or Mexico City or somewhere in the Alps  
I'd tag it as such. I thought the original issue of accuracy was one  
of precision (either via tool measurement or in human recollection).

Not one of being able to define a "geo" that accurately represents  
the floorplan of Yankee Stadium or the whole of Antarctica but of  
accurately reflecting if a designation was accurate enough to make a  
determination if a specific seat in yankee stadium, "somewhere in the  
bleechers", or just "near the stadium as i was walking around before  
the game" or "i need to mark the bronx somehow so left me zoom out  
and drop a marker from the 50k foot view"


(Forgive me if I may have read more into the discussion due to my own  
biases/concerns)
