A "clarification" rides below Malcolm Gladwell's 2010 article "Small Change": "This piece’s account of the Greensboro sit-in comes from Miles Wolff’s 'Lunch at the Five and Ten' (1970)."

The enigmatic media bloggers @crushingbort and @blippoblappo Thursday made a case that article insufficiently credited Wolff's book. New Yorker Editor David Remnick told Poynter "In retrospect, for example, we should have credited Miles Wolff’s 1970 book about Greensboro, because it’s central to our understanding of those events."

So if you were unclear on that point, consider yourself less so.
