As a volunteer member of NCDD, I deployed an instance of an open source dialogue platform as part of a conversation that cited technology as a bottleneck to scaled collaborative dialogue. Ultimately, the platform didn't gain much traction. The lack of adoption reimpressed the fact that technology isn't a limiting factor to online collaboration. Coordination is. Existing networks have the advantage that coordination costs are already paid. When dialogue is distilled into an enjoyable game people can play together, we'll see new levels of dialogue, and hopefully higher resolution communication.
