There is a huge difference between what the two of us are describing though.
Whereas getting organised to do some grassroots Discourse evangelism would require just a few hours from me and whoever wants to join the effort, what you describe is a massive engineering project which would also be a huge risk. Facebook tried to make such a thing with Rooms. They failed, and they didn’t even have to make money from it!
For the foreseeable future we are only in the community hosting business, not in the community generation/curation/management business such as Reddit, or Imzy.
