There could be more public community centers in America that people could visit just to exist with other people. These community centers could be open 24/7 to accomodate people of all sleep schedules. Especially as we become more dependent on technology, and spend most of our time sitting in front of a screen, why do we have to sit isolated in our own homes to do it?
In college, I spent most of my time in such wifi enabled common areas, and quite enjoyed it. The most similar thing we have to that right now that I see are coffee shops. these are nice, but it is a requirement to buy a drink in order to sit there, and seating is usually limited. There are also public libraries, but they tend to be dirty, and talking isn't allowed. Obviously, a big challenge would be in keeping the place from being decimated by random miscreants, and keeping it open even though it doesn't offer a product or service. Perhaps the supervisors could charge a small admittance fee, and could be free to remove from the premises any people who destroy the property.
Reward: A more connected community.
