Resources: Add Value.
I like to learn stuff from someone who can do what I want to do and will answer my questions. I don't like extraneous material cluttering the path to my goal. The greatest achievements are made through cooperation. We all stand on the shoulders of those who cooperated to achieve the point where we should start. And the greatest achiever will lift us there, so we can lift the next achiever. We disserve ourselves, our ancestors, and our progeny when we hoard our results and pretend to be smarter than the next achiever, when rather than showing where we left off and where he should start, we instead slow our collective progress by placing the next achiever at our feet, and requiring that he review the mistakes we have already made and learned from. Time is too short. In a cooperative efficient society, no one reinvents the wheel.
