@bmann yes! @mozilla and @medium have instances, who else?
governments and cities... somehow, I feel like they'll be the last to the party. Have you seen any examples of such? the only location-based instances I've encountered so far are grassroots efforts from locals.
and completely agree on the tooling and systems... it will be interesting to see what springs up for the non-technical aspects of adminning an instance, like policy drafting, community management, etc.
