[NAFDA] The place for casting and other vague spoilers, for those who merely want to wade, not drown, in the spoiler sea. Casting spoilers are okay, as are non-plot-point specific spoilers (like, "Joss says the theme of Season 7 is ____"). White-fonting is always appreciated. Information from Magazines like TV Guide may also come up.
