To many a white folk, what Michael Wilbon refers to as "Black World" isn't so much a mystery as something of which we're completely unaware. It might as well be a deep-sea ecosystem, so alien and unseen it is.
In the context of the Grant Hill/Fab Five dustup, Wilbon does a good job of lowering a bathysphere into Black World—explaining some critical, even self-destructive, Black World dynamics.
You can tell his audience is primarily white people because he speaks of black socioeconomic strata in terms we're sure to understand: sitcom characters. I winced, but more at that choice's probable necessity than at the choice itself.
