Of all the auspice lists I've been on, and that's most of them, Ragabash is the talkiest, followed by Galliard. Usually when some drama thing blows up on the IC list, or just before. Silver Fang list is dead, until it's not, then they say the same thing many times over for a week or two...then it goes dead again.
Still the deadest has been the Kinfolk Network, which has only had one thing on it...and that's when someone sent something there by mistake.
