There is a new focus on neighbours and neighbourliness, perhaps driven by the twin forces of globalisation and technology. I like this approach by Seth Stevenson at Slate on Nextdoor:
Tech entrepreneur Nirav Tolia noticed that we increasingly seem to prefer rubbing elbows online—instead of in real places where real elbows might really rub—and saw a business opportunity. In late 2010, he created a service called Nextdoor. It's a social network that attempts to webify the original social network: the neighborhood. There are now Nextdoor sites in more than 6,500 communities in 49 states (not clear what's up with those anti-communitarian South Dakotans). All of them were launched by regular folks who sought a way to connect with their neighbors, but didn't want to ring doorbells or make small talk in the elevator.
