Thank you @Scott for letting me (and others, I guess) know about http://www.discourse.org/ (discourse). I glanced at it, it looks attractive, seem to have new features, etc., however I am not an expert. Thus I want to propose an intermediate project MetMO_tst--based software-wise on discourse--which would be a stepping stone possibly leading toward a better Meta called ultimately MetMO. Thus MetMO_tst would be a simulation of the future MetMO:
- A team of $2$ to $6$ people would create, own and manage MetMO_tst based on discourse, which would simulate the possible future MetMO.
- For the sake of the software and otherwise simulation, the team members would perhaps have more than user ids, to imitate having more users. Etc.
- There would be some other supporters who would simulate regular users to assist the test project. Call these other participants consultants. Consultants would be admitted only when invited by the managers.
- The simulation, when the time is ripe, would allow the managers to decide about starting or not MetMO. Perhaps first a discussion can take place on the present Meta and Tea, and MetMO can be open for reading only, to present the results of the simulation, and the ideas for the near future.
DISCLAIMER Just in case, I am not going to be a MetMO_tst manager. Possibly, I could be among consultants but I am not too much interested one way or another. However, I really would like some people, including @ScottMorrison, to create the simulation--MetMO_tst.
