First edit for continuity/content. Re-organized definitions.  Placed discussion of the meaning of a community at end of relationships section and retooled.  Moved public outreach plug to its own subsection of the summary.  Many miscellaneous wording/ordering edits.
Added in some content from an old set of notes about these ideas.  List of guiding principles could be useful/relevant. Other additions are related to the reviews-get-reviewed concept.
