The reason the Longue is a "quiet" room is so you can log in, get your bearings and then go to the room that fits your roleplay best once you're settled for it.
I have nothing against people sitting around in it to see who logs in, nor helping newbies who appear in it and can't work out how to shift rooms etc. However since it is essentially a login apparatus and a first impression it's not room for general non-sense silliness, political discussion, etc.
Off topic areas go at the end of discussion sections, not at the beginning. If we get new people logging in and their first impression of the chat is that people sit around blabbing then they're quite likely to dismiss the place as another normal chat and leave it.
I don't want to hush the longue, both because I am a very busy guy so it'd chew a lot of time and I quite like the idea that someone new to the site can get help from people in the entry room who haven't "jumped in" yet.
However that does require that people treat it for what it is, a room you log into before you go into other rooms. Not a general OOC chit-chat room. All OOC discussion can go in the Nexus whether it be a serious discussion on plots, a gaming plan etc, or people wanting to discuss whether a new albumn is awesome or not.
