Metaphysical Geekery

Does anyone know of good forums online for reasonably "advanced" (ie, not just 101 and 102 type introductions to stuff), in-depth and knowledgeable discussions of metaphysical subjects? As an example, I would have considered the old Barbelith Temple to be one such place, though these days it seems largely defunct.  I've stumbled across Liminal Nation which looks like it has promise but the application process makes me somewhat hesitant.  Mostly because they want a bio, and I've always hated writing bios of myself.  I never know what to put, how to sum myself up, particularly as it pertains to my metaphysical practices.

I'd prefer not to have to wade through much fluff.  I'd like a high signal to noise ratio.  I'd like critical thinking to be the rule rather than the exception.  Basically, I want to find places that are already like what I have always wanted the WanderingPaths list to become.  

Anyone know of such a place?
