I set up a Facebook page for those interested in the LDWA some 18 months ago ...
http://www.facebook.com/group.php?gid=44930889351&ref=ts
It currently has 239 members and, like the forums, it has bursts of activity.
I must stress this is a page for "fans" of the LDWA, not an officially sanctioned one. This, I think, is the best approach. And I would see no reason why each Group should not have one.
