@brennen But I'm not sure the points/metric/gamified aspect of it is the problem. Compare StackOverflow to Wikipedia, in terms of how contributors are treated. SO actually has a feedback mechanism that lets (some) people learn how to do it and get value out of asking & answering. On Wikipedia—no points, no trophies, no feedback, no way to learn, just reverted edits and frustrated ex-editors.
Would you agree with this assessment, and the general idea that points might not be the problem here?
