No, most Philly folks get baffled by Pittsburghese. To me, my manager from Philly sounds like someone from the cast of Jersey Shore, though I'm sure he would disagree. I don't hear the finer nuances.

I grew up in WV, but, as a young adult living elsewhere, most people thought that I had a Pittsburgh accent or thought that I couldn't be from WV because I didn't sound southern. To me, northern WV is different than Pittsburgh. The WV Appalachian accent is different than a Deep South accent. But, not everyone will hear it.
