I hate to be pedantic, but you're misreading the parent post (they didn't say "diameter" nor "perimeter" and neither really makes sense in this context) and then being confrontational based on your misreading. You and the parent post both have good points otherwise, best to keep it a friendly discussion.

I missed the "square" in the "square mile" phrase and thought the OP was referring to a distance (hence my reference to Palo Alto) and not area - my bad.
