Could pulling Wi-Fi improve discourse and create intellectual pursuits?
I believe the underlying issues are much more complex and probably cultural. Just pulling WiFi from coffee shops is not enough to reverse the increasing trend towards less and less interaction among people. And it isn't as if spending time online means not interacting. Chat rooms, messenger and email do allow people to interact and in future it will be probably much more closer to the real thing, face to face conversations. Also, probably this phenomena is more a anglo-saxon thing. Out here in Spain you don't find a lot of cafes that have people with laptop or people not chatting animatedly.
