> (someone else used the term "metro" which humorously includes the suburbs, but whatever)
Not really sure where the humor is being found. There are areas where suburbs grew into their own cities that now blend back into the larger urban area they were once separated from. They are no longer suburbs, and it is now more than one city, so metroplex/metropolitan area is the term used.
I was referring to someone saying "works for suburbs I'm guessing - I don't see how it helps out in metro areas?".
A "metro area" is by definition the overarching container (often including multiple cities and the suburbs of those cities, such as the Bay Area metro area), most definitely containing said suburbs. So if something "works for the suburbs", it works for the metro.
