Neil has been talking about how much the Gnome community has gotten out of discourse. His experience has been positive enough that as an individual developer I'd be interested in using a pilot.
I want to stress that I'm not volunteering to do the work of setting up such a pilot. I could imagine such a thing starting out being entire disconnected in phase 0. And trying it out and getting some people to give feedback. If that were sufficiently positive, then working on a pilot where one list were moved to discourse to see how it works.
