For anyone involved in group discussions, planning, project writing or anything else that happens by collaboration, this might just be the online tool to do the job. When I posted a link to the video I thought then that it had real potential if it could live up to its billing. Well, my early looks suggests that Google Wave might just be able to do exactly what I want it to do.
I've set up some waves for things like Advent planning, deacons' meetings and thinking about pastoral care. The true test will come when other people start interacting with these waves.
I'll keep you posted!
