One thing mentioned is that some people make extensive use of private modes of communication with project leaders. I've fallen prey to this as a contributor myself, so much that I've now made it my policy to never converse privately unless it's related to a security issue.
I think another important point is multiple channels of discussion. The project I work on has a forum where people can ask for help installing or with other issues they have. If they find a bug or have a feature request, it goes on our issue tracker on GitHub.
