I think one thing we should work on, is being absolutely religious about requiring, say, 2 reviews for every nontrivial contribution. We currently seem to have a significantly increased submission rate, and at the same time the number of reviews per patch has gone down substantially. I think the "honor" system has failed in that regard.
It failed because its never mentioned or even attempted to be enforced.
Some way to balance submissions against reviews is now essential.
If we believe in "peer review", we need peers that review.
