Survey Available Materials for Developers, Users, Contributors, Participants

I have been collecting samples of web sites and related information that has appealing approaches to aspects of community support that may be adaptable for us.

This is an open-ended task with the JIRA issue used as a collection point for contributions via comments.

I can imagine that a wiki would be good for this but that's sort of a chicken-egg problem, since organizing a wiki is something to collect information about.
