I don't mean writer's circles, or "auditioning sites", although some of these have forums tacked on as a by the by. Usually places to talk about the beardy philosophy of writing are moribund places as many writers are just not joiners.
Does anyone know of a healthy writer's community that talks about the imponderables of writing and does polls etc. I am particularly interested in one for writers of genre fiction and ones with a particular bent towards storytelling and experimentation in that field but I'm sure that writers.se's lit fic authors and technical writers could benefit from knowing if there are communities for them too.
(Incidentally I know also about Nanowrimo. I find many of the healthy discussion among Nano participants is all about getting that 50k done, not my issue I can get stuff done, I mean something like experimental role playing forum "The Forge" but for storytellers.)
