I’d be interested in the answer to this question, too! I’m the founder of Youth Power Coalition and we’re actually a startup working to build our Discourse platform to be a place where e-governance happens so what you wrote is the dream! We’re a startup, so we’re 20 team members at the moment, but we always ask, how are we building for when we’re 10,000 members? 100,000 members? 1,000,000 members?
Check out our forum at hub.youthpowercoalition.org. Read up on the collaboration features I’m experimenting with here.

We’re probably also going to rely heavily on how we scope out our projects via the Kanban method.
