I am cowardly enough that I haven’t joined in — a friend told me it had already started (but r/fantasy had announced that it would be running sometime in November). I am a dinosaur, from the time when authors were told never to react to or interact with reviewers of their books — something I saw the wisdom of when I encountered the first goodreads author meltdown many years later. Or the next one. Or the one after that >.<.
And also: reader space and author space really only overlaps in the spaces I oversee. Readers should have a place where they can, oh, hate author choices and discuss them without being afraid of a) hurting author feelings or b) angry/upset authors.
But I thought I would mention it here for people who either want to read or join in.
