An interesting segment on NPR drew an analogy between Twitter ties and airline hub maps. A recent study from the University of Toronto found that airline connections between your city and the rest of the world predict your Twitter connections. For example, if you live in New York, you’re more likely to have followers in London (a popular airline route) than followers in a small town U.S. city, where an airline route does not exist.
The study also suggests that existing airline routes predict that people in these two connecting cities have common interests, and are more likely to follow each other on Twitter.
How does your Twittersphere match up?
