Now Then is an independent Sheffield-based arts and community magazine. They are monthly, good chaps and have an out of date website. It is part of the Opus Productions media empire. For the first issue of the magazine, last year, I wrote them an article about something that has interested me for a long time: small worlds. Specifically I’d been thinking about social networks and what the Watts and Strogatz small-world result had to tell us about them. The article is now here, should you wish to read it. It is pretty upbeat. I think if I had more room and less inclination to try to be positive I would include something about how we tend to organise our social worlds so that it seems, from the ‘ground-level’, that we are talking to everyone important, but in actually fact we are ignoring — completely estranged from — most of the people we are physically close to, insulated in comforting small worlds.
