I would bet that most people on this thread have answered few stack overflow questions freely. Plenty of people contribute to Wikipedia , If I see simple mistakes in a project wiki or readme people submit the pull request because github makes it easy to do. It is matter of UX and openness towards contribution. MDN never felt like it needed my contribution, not once I thought that a) I could actually add value b) my contributions were welcome. Until a couple of days back I and many others did not know even that MDN took wiki style contributions.
