Browsing the social graph

I've made an attempt at writing up this user story here.

https://github.com/w3c-social/SoLiD/blob/master/UserStories/BrowsingTheFriendshipGraph.md

It is now the 2nd user story marked as interop - online on our aggregate
page:

Feedback is welcome.  Please feel free to comment, ask questions, or verify
the information presented.

The friendship graph is not specifically related to SoLiD.  The friendship
graph extends many million users over hundreds of domains.  Indeed it
extends to GNU Social, identi.ca and other sites that form the basis of
Activity Pump.

IMHO this is a fundamental foundation to the social web.  However, there is
a big difference between read only profiles and profiles that you can write
information to.  The SoLiD spec aims to allow more profiles to accept
social changes on the web.
