Then if you have the information, why not make use of it? It wouldn't be rocket science to extrapolate from the co-ordinates an approximate location and publish it. Even those shy, retiring users surely couldn't object to that?
Besides, those that post screenshots with "Home" in the middle of the picture are already giving away their approximate locations, at least sufficient to get an idea where they might be.
It's better than blithely showing a map with a user in France appearing to be in Germany, just because that's where his IP is located... no use to anyone!
