Technology Is Not Driving Us Apart After All - NYTimes.com: It turns out that people like hanging out in public more than they used to, and those who most like hanging out are people using their phones. On the steps of the Met, “loiterers” — those present in at least two consecutive film samples, inhabiting the same area for 15 seconds or more — constituted 7 percent of the total (that is to say, the other 93 percent were just passing through). That was a 57 percent increase from 30 years earlier. And those using mobile phones there were five times as likely to “loiter” as other people. In other words, not that many people are talking, or reading, texting or playing Candy Crush on the phone, but those who do stick around longer. (In the case of Bryant Park, it doesn’t hurt that the area is no longer an open-air drug market — a major problem that P.P.S. was trying to root out in the ‘80s.)
According to Hampton, our tendency to interact with others in public has, if anything, improved since the ‘70s.
