Facebook, sure, but Uber and AirBNB? I don't see how Uber has displaced some community function. AirBNB is arguably destructive to communities, but again how was community fulfilling the need it attempts to address?
with classified ads? or calling the local tourist office? Like people didnt rent a house for their holiday before airbnb
Before Uber it was totally normal to ask someone, even an acquaintance, for a ride to the airport.
