This is a good guide for a starter, but doesn't address dealing with rock stars themselves, which is what's required if your contribution is going to be merged.

And that usually requires the skin of a pachyderm, and the patience of a fox. The reality of today is that the world idolizes idols. Idols in turn become arrogant. Their worst trait is belittling others' contributions - especially when they're better than the rock star could've done.

I have no solution. I'm pointing out what I see as an omission from an otherwise useful post.
