Cyn is taking a leave of absence, Monica was removed, the others have stepped down...
So now what?
The simple answer is just no.
While at least I still technically have a diamond, I for one am merely waiting for a Stack Exchange employee to remove it, and I have not performed any moderation activities on either site where I've had a diamond, since I posted about my stepping down about 46 hours ago. Both my own and Neil's diamond moderator access has now been revoked.
What happens next is up to Stack Exchange Inc. There has been much speculation in different places, but as far as I can tell, the official update posted a few hours ago does not address that issue at all. (A second apology and update was posted later, but also does not appear to address this.)
