I'm recognizably cynical, but I've found that people generally don't like to do work, but like to take credit for completion.
For early-stage initiatives (like organizing events, building community, or leading projects), the motivator kind of takes the role of a martyr. You gotta dump in a whole fuckton of unrecognized labour, which others will enjoy more than yourself.
It's once things become stable/institutionalized that you might see eager young(er) folks bring their own efforts & ideas.
