Recently I posted about Glasgow to Detroit, a documentary by Don MacKeen concerning urban farming in these two post-industrial cities. Don is an American expat living in Glasgow and had emailed me about the film. After the post appeared here, Scottish Televison in Glasgow emailed me asking how to contact Don. I sent the info and they contacted him.
And that is the power of blogging. Information bounces across the planet and then sometimes bounces, in altered form, to where it began!
Update: Read the Scottish Television article about Don and the movie.
