I think this will either work complementarily with or replacing
our 'links' lists. The point is to provide some summary information
about each group.

My focus right now is to provide the information from the point of
view of somebody trying to understand how all these groups fit
together, rather than somebody totally new to the Linux community.

So I think we will end up having an "end-user resources" and an
"advocacy groups" list, which emphasize different aspects, and
probably have different (tho overlapping) sets of links.

Anyway, this is a very crude start on the groups page. Comments
on style as well as content appreciated.
