Without Their Permission: How the 21st Century Will Be Made, Not Managed
By Alexis Ohanian (Business Plus, $27)

Alexis Ohanian is a fan of the Internet for good reason: He co-founded Reddit.com when he was 20, then sold it for big bucks to Condé Nast less than two years later. But, as Ohanian explains in this quirky startup guide, he loves the creativity the Internet can unleash more than the earnings it can generate. Ohanian pokes gentle fun at himself and furnishes the book with its own mascot, useful case histories and pointers — as well as the tragic story of how his mother’s death from a brain tumor inspired a carpe diem attitude. His blunt message rings true: “Magic happens when you give a damn.”
