Excellent project to boost engagement in local issues. Wonder if we could run something like this in Liverpool and even provide some low-tech feedback (in addition to the high-tech website side of things) with regularly printed and updated posters - pick places to advertise the questions, but then have a network of volunteers to print out updates and paste them over the adverts on a daily or every-few-days basis
A good overview of the Open Space method of conference/meeting organisation. I like the "chairs are all set out in a circle" format - dressing the venue will be an important part of working out how the long-conference proceeds.
