I've seen a few of these now over the years, and I've come to believe a successful implementation should combine argument mapping, consensus building, and a trust network. Just framing an issue and having a comments section isn't enough; that form is ubiquitous across the Internet yet hasn't proven a viable way on its own to actually make decisions.
I agree, we have a long roadmap ahead and all your points should be in it. If you wish to contribute, by all means github.com/democracyos. It's an open source project.
