Esteemed nonfiction writer Malcolm Gladwell, whose works include sprawling sociological bestsellers David & Goliath and The Tipping Point, is celebrating the patronage of Gucci Mane after the pair exchanged compliments on Twitter. Last night, Gladwell was tweeted a picture of Gucci carrying a copy of David & Goliath, to which he responded, “This might be the greatest thing that has ever happened to me.” Gucci replied this morning, “you my favorite author.” See the tweets below.
