My guess is it doesn't really matter either way. Software projects are so complex that just understanding them is a full time job. The code will be an incomprehensible blob to anyone who hasn't put many hours into understanding it. People may be enthusiastic at first and screw around with your project for a couple of weeks, but eventually they will stop caring. So the maintainer ends up doing the vast majority of the work, regardless of whether a project is open or not. I have no data to back up that claim, it's just my gut feeling. Has Reddit gotten substantial code contributions as a result of open-sourcing its stuff?
