Carman Pirie has an interesting post about how he used ning to support a real world Open Space event. Like Carman, I'm concerned not to let recording of conversations become an impediment to participants, so I really liked his ideas for keeping it streamlined, whilst offering hosts the chance to record mini videos to the site.

The ning site Carman used is private, but it sounds like it has added a lot to the event - and very much in keeping with allowing each participant to take responsibility and contribute.

Chris Corrigan likes it too!
