Meta Stack Exchange (which emerged from Meta Stack Overflow after the Stack Exchange network was spawned) is great; it gives you a chance to talk about the Stack Exchange network in a disconnected forum so that you don't have to break the fight club rules of talking about Stack Exchange sites on Stack Exchange sites, and can do so generically.
But what about the cases when you want to talk about Meta Stack Exchange? I would assume that the same rules apply in that you cannot talk about Meta on Meta. So where is a guy to go?
