Ohhh no, the old names are pretty much never referred to, at least as far as I've heard. Not once. No one would know what the other was talking about most likely
The old names were just so much nicer. I forget what 17th's was, but it was wayyyyy better than some stupid number. Maybe Broadway? I don't remember.
I admit that numbers are more comprehensive for directions, but come on, the human quality of beautiful names, some with historic meaning, should trounce that crap.
