Email subject heading: "(User Tyrannis's real name) is sharing with you on Google+!"
There is a top-secret facebook group that is, indeed, reasonably active. I think there's a page too, but that's probably dead.
The actual G+ page for RW is dead as a post, so the group mostly consists of us talking about completely random things.
the one i know about has some posts, and isn't "dead", though i only recognize a couple of names on it.
