Can you elaborate? I only removed the qualifier ("written by non-native / lazy / busy devs"), since almost any text that has not been copy-edited can be improved by doing just that, which requires little or no domain knowledge. Also don't undervalue documentation feedback. Everyone makes first contact with a project only once, and the feedback of this "onboarding" can be invaluable and point to critical shortcomings of documentation.
