From his TED.com profile
His influential book Africa Unchained has helped unleash a new wave of activism and optimism -- especially in the African blogosphere, where his notion of cheetahs-versus-hippos has become a standard shorthand. The "Cheetah Generation," he says, is a "new breed of Africans," taking their futures into their own hands, instead of waiting for politicians to empower them. (He compares them to the previous "Hippo Generation," who are lazily stuck complaining about colonialism, yet doing nothing to change the status quo.)
