@ashleykolodziej in the thread with @dahukanna I mentioned "movement" vs. "community", spontaneous emergence and DoOcracy.
That sounds a bit overly casual, but just indicates it is up to anyone to give their twist to the SX field exploration. And ideally based on having the incentives to do so, and thus intrinsic motivation.
More concretely I'm thinking on having something akin to working groups (called Fellowships) with clear scope and focus, based on interest for particular themes within SX.
