I think there are different expectations with respect to " in depth" discussion that is all. The Senate expects it because it is a niche forum designed for that purpose and that is the focus of the mods, whilst the JCC does not expect it but clearly that does not mean that "in depth discussion" does not or cannot happen there. People will gravitate to whichever forum suits them. Just because somebody doesn't frequent the Senate doesn't mean they are incapable of doing so it just means they aren't interested or couldn't be bothered. At the end of the day it's always going to be a question of whether the thread topics are of interest. The Senate mods can relax the "in depth discussion" criteria somewhat but that won't matter if all of the thread topics are boring or are limited to a specialised field.
