Narrative document for Social Diagram ready for input

There is a first version of the narrative for the social diagram set for
open editing here<https://docs.google.com/document/d/1skxBTQRWAfYRKsf1LTpYguqBo4ddgESUoy9ASgCPJpA/edit>.
 Additional input and edits are of course very appreciated.

I also added a link to the groups home page here:
